Add a language switcher using PrimaryLanguageOverride (#10309)
## Summary of the Pull Request

This PR adds a global "language" setting, which may be set to any supported BCP 47 tag.
Additionally a ComboBox is added to the settings UI under "Appearance", listing all languages with their localized names.

This PR introduces one new issue: If you change the language while the app is running, the UI will be in a torn state, as not all UI elements refresh automatically if the `PrimaryLanguageOverride` is changed.

## PR Checklist
* [x] Closes #5497
* [x] I work here
* [x] Tests added/passed
* [ ] Documentation updated. If checked, please file a pull request on [our docs repo](https://github.com/MicrosoftDocs/terminal) and link it here: #xxx
* [x] Schema updated

## Validation Steps Performed

* UI language changes when changing the "language" in settings.json before starting WT / while WT is running. ✔️
* "language" field is removed from settings.json if "Use system default" is selected. ✔️
* "language" field is added or updated in settings.json if any other language is selected. ✔️
* Removes qps- languages if debugFeatures is false. ✔️
* Correctly refreshes all UI elements with the new language.

Add support for branch- and branding-based feature flagging (#10361)
This pull request implements a "feature flagging" system that will let
us turn Terminal and conhost features on/off by branch, "release" status
or branding (Dev, Preview, etc.).

It's loosely modelled after the Windows OS concept of "Velocity," but
only insofar as it is driven by an XML document and there's a tool that
emits a header file for you to include.

It only supports toggling features at compile time, and the feature flag
evaluators are intended to be fully constant expressions.

Features are added to `src\features.xml` and marked with a "stage". For
now, the only stages available are `AlwaysDisabled` and `AlwaysEnabled`.
Features can be toggled to different states using branch and branding
tokens, as documented in the included feature flag docs.

For a given feature Feature_XYZ, we will emit two fixtures visible to
the compiler:

1. A preprocessor define `TIL_FEATURE_XYZ_ENABLED` (usable from MIDL,
   C++ and C)
2. A feature class type `Feature_XYZ` with a static constexpr member
   `IsEnabled()` (usable from C++, designed for `if constexpr()`).

Like Velocity, we rely on the compiler to eliminate dead code caused by
things that compile down to `if constexpr (false)`. :)

Michael suggested that we could use `WindowsInbox` as a branding to
determine when we were being built inside Windows to supplant our use of
the `__INSIDE_WINDOWS` preprocessor token. It was brilliant.

Design Decisions
----------------

* Emitting the header as part of an MSBuild project
   * WHY: This allows the MSBuild engine to ensure that the build is
     only run once, even in a parallel build situation.
* Only having one feature flag document for the entire project
   * WHY: Ease.
* Forcibly including `TilFeatureStaging` with `/FI` for all CL compiler
  invocations.
   * WHY: If this is a project-wide feature system, we should make it as
     easy as possible to use.
* Emitting preprocessor definitions instead of constexpr/consteval
   * WHY: Removing entire functions/includes is impossible with `if
     constexpr`.
   * WHY: MIDL cannot use a `static constexpr bool`, but it can rely on
     the C preprocessor to remove text.
* Using MSBuild to emit the text instead of PowerShell
   * WHY: This allows us to leverage MSBuild's `WriteOnlyWhenDifferent`
     task parameter to avoid changing the file's modification time when
     it would have resulted in the same contents. This lets us use the
     same FeatureStaging header across multiple builds and multiple
     branches and brandings _assuming that they do not result in a
     feature flag change_.
   * The risk in using a force-include is always that it, for some
     reason, determines that the entire project is out of date. We've
     gone to great lengths to make sure that it only does so if the
     features _actually materially changed_.

[Defapp] Use real HPCON for PTY management; Have Monarch always listen for connections (#10170)
[Defapp] Use real HPCON for PTY management; Have Monarch always listen for connections

## PR Checklist
* [x] Closes #9464
* [x] Related to #9475 - incomplete fix
* [x] I work here.
* [x] Manual test

## Detailed Description of the Pull Request / Additional comments
- Sometimes peasants can't manage to accept a connection appropriately because I wrote defterm before @zadjii-msft's monarch/peasant architecture. The simple solution here is to just make the monarch always be listening for inbound connections. Then COM won't start a peasant with -Embedding just to ask the monarch where it should go. It'll just join the active window. I didn't close 9475 because it should follow monarch policies on which window to join... and it doesn't yet.
- A lot of interesting things are happening because this didn't have a real HPCON. So I passed through the remaining handles (and re-GUID-ed the interface) that made it possible for me to pack the right process handles and such into an HPCON on the inbound connection and monitor that like any other ConptyConnection. This should resolve some of the process exit behaviors and signal channel things like resizing.

Introduce serialization for actions (#9926)
## Summary of the Pull Request

This PR builds on the `ActionMap` PR (#6900) by leveraging `ActionMap` to serialize actions. From the top down, the process is now as follows:
- `CascadiaSettings`: remove the hack of copying whatever we had for actions before.
- `GlobalAppSettings`: serialize the `ActionMap` to `"actions": []`
- `ActionMap`: iterate over the internal `_ActionMap` (list of actions) and serialize each `Command`
- `Command`: **THIS IS WHERE THE MAGIC HAPPENS!** For _each_ key mapping, serialize an action. Only the first one needs to include the name and icon.
- `ActionAndArgs`: Find the relevant `IActionArgs` parser and serialize the `ActionAndArgs`.
- `ActionArgs`: **ANNOYING CHANGE** Serialize any args that are set. We _need_ each setting to be saved as a `std::optional`. As with inheritance, this allows us to distinguish an explicit setting to the default value (sometimes `null`) vs an implicit "give me the default value". This allows us to serialize only the relevant details of each action, rather than writing _all_ of the args.

## References
- #8100: Inheritance/Layering for lists
   - This tracks layering and better serialization for color schemes _and_ actions. This PR resolves half of that issue. The next step is to apply the concepts used in this PR (and #9621) to solve the similar problem for color schemes.

Introduce til::rle - a run length encoded vector (#10099)
## Summary of the Pull Request

Introduces `til::rle`, a vector-like container which stores elements of
type T in a run length encoded format. This allows efficient compaction
of repeated elements within the vector.

## References

* #8000 - Supports buffer rewrite work. A re-use of `til::rle` will be
  useful as a column counter as we pursue NxM storage and presentation.
* #3075 - The new iterators allow skipping forward by multiple units,
  which wasn't possible under `TextBuffer-/OutputCellIterator`.
  Additionally it also allows a bulk insertions.
* #8787 and #410 - High probability this should be `pmr`-ified
  like `bitmap` for things like `chafa` and `cacafire`
  which are changing the run length frequently.

## PR Checklist

* [x] Closes #8741
* [x] I work here.
* [x] Tests added.
* [x] Tests passed.

## Validation Steps Performed

* [x] Ran `cacafire` in `OpenConsole.exe` and it looked beautiful

Add property to control dropdown speed of global summon (#9977)
## Summary of the Pull Request

Adds the `dropdownDuration` property to `globalSummon`. This controls how fast the window appears on the screen when summoned from minimized. It similarly controls the speed for sliding out of view when the window is dismissed with `"toggleVisibility": true`.

`dropdownDuration` specifies the duration in **milliseconds**. This defaults to `0` for `globalSummon`, and defaults to `200` for `quakeMode`. 200 was picked because, according to [`AnimateWindow`](https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-animatewindow): 

>  Typically, an animation takes 200 milliseconds to play.

Do note that you won't be able to interact with the window during the animation! Input sent during the dropdown will arrive at the end of the animation, but input sent during the slide-up _won't_. Avoid setting this to large values!

The gifs are in Teams.

## Detailed Description of the Pull Request / Additional comments

I had the following previously in the doc comments, but it feels better in the PR body:

- This was chosen because it was easier to implement and generally nicer than:
  * `AnimateWindow`, which would show the window borders for the duration of
    the animation, and occasionally just plain not work. Additionally, for
    `AnimateWindow` to work, the window much not be visible, so we'd need to
    first restore the window, then hide it, then animate it. That would flash
    the taskbar.
  * `SetWindowRgn` on the root HWND, which caused the xaml content to shift to
    the left, and caused a black bar to be drawn on the right of the window.
    Presumably, `SetWindowRgn` and `DwmExtendFrameIntoClientArea` did not play
    well with each other.
  * `SetWindowPos(..., SWP_NOSENDCHANGING)`, which worked the absolute best for
    longer animations, and is the closest to the actual implementation of
    `AnimateWindow`. This would resize the ROOT window, without sending resizes
    to the XAML island, allowing the content to _not_ reflow. but for a
    duration of 200ms, would only ever display ~2 frames. That's basically
    not even animation anymore, it's now just an "appear". Since that's how
    long the default animation is, if felt silly to have it basically not
    work by default.
- If a future reader would like to implement this better, **they should feel
  free to**, and not mistake my notes here as expertise. These are research
  notes into the dark and terrible land that is Win32 programming. I'm no expert. 

## Validation Steps Performed

## Detailed Description of the Pull Request / Additional comments

I've replaced the `dictionary` directory with `allow` and `reject`. When terminal got check-spelling, I didn't have a way to do `allow`/`reject` (but they were added a while ago). With this release, the bot will complain about items that are in user managed files that wouldn't be valid, this is mostly `-`s in dictionary files, but it also includes numbers `0`..`9` and `_`. If a specific token needs to be accepted but not its sub-elements, the item should be added to `patterns.txt` instead  (`D2DERR_SHADER_COMPILE_FAILED` is an example).

With this version, check-spelling defaults to only considering tokens with at least 3 letters. It's possible to tune it back to 2 (or even 1), but in testing, the 2 character tokens have ended up not being worthwhile.  (This can be [adjusted](https://github.com/check-spelling/check-spelling/wiki/Configuration#shortest_word) if it turns out that people manage to misspell two character tokens often enough to justify checking them.)

<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed

Implement PGO in pipelines for AMD64 architecture; supply training test scenarios (#10071)
Implement PGO in pipelines for AMD64 architecture; supply training test scenarios

## References
- #3075 - Relevant to speed interests there and other linked issues.

## PR Checklist
* [x] Closes #6963
* [x] I work here.
* [x] New UIA Tests added and passed. Manual build runs also tested.

## Detailed Description of the Pull Request / Additional comments
- Creates a new pipeline run for creating instrumented binaries for Profile Guided Optimization (PGO).
- Creates a new suite of UIA tests on the full Windows Terminal app to run PGO training scenarios on instrumented binaries (and incidentally can be used to write other UIA tests later for the full Terminal app.)
- Creates a new NuGet artifact to store trained PGO databases (PGD files) at `Microsoft.Internal.Windows.Terminal.PGODatabase`
- Creates a new NuGet artifact to supply large-scale test content for automated tests at `Microsoft.Internal.Windows.Terminal.TestContent`
- Adjusts the release pipeline to run binaries in PGO optimized mode where content from PGO databases is leveraged at link time to optimize the final release build

The following binaries are trained:
- OpenConsole.exe
- WindowsTerminal.exe
- TerminalApp.dll
- TerminalConnection.dll
- Microsoft.Terminal.Control.dll
- Microsoft.Terminal.Remoting.dll
- Microsoft.Terminal.Settings.Editor.dll
- Microsoft.Terminal.Settings.Model.dll

In the future, adding `<PgoTarget>true</PgoTarget>` to a new `vcxproj` file will automatically enroll the DLL/EXE for PGO instrumentation and optimization going forward.

Two training test scenarios are implemented:
- Smoke test the Terminal by just opening it and typing a bit of text then exiting. (Should help focus on the standard launch path.)
- Optimize bulk text output by launching terminal, outputting `big.txt`, then exiting.

Additional scenarios can be contributed to the `WindowsTerminal_UIATests` project with the `[TestProperty("IsPGO", "true")]` annotation to add them to the suite of scenarios for PGO.

**NOTE:** There are currently no weights applied to the various test scenarios. We will revisit that in the future when/if necessary.

## Validation Steps Performed
- [x] - Training run completed at https://dev.azure.com/ms/terminal/_build?definitionId=492&_a=summary
- [x] - Optimization run completed locally (by forcing `PGOBuildMode` to `Optimize` on my local machine, manually retrieving the databases with NuGet, and building).
- [x] - Validated locally that x86 and ARM64 do not get trained and automatically skip optimization as databases are not present for them.
- [x] - Smoke tested optimized binary versus latest releases. `big.txt` output through CMD is ~11-12seconds prior to PGO and just over 8 seconds with PGO.

Introduce ActionMap to Terminal Settings Model (#9621)
This entirely removes `KeyMapping` from the settings model, and builds on the work done in #9543 to consolidate all actions (key bindings and commands) into a unified data structure (`ActionMap`).

## References
#9428 - Spec
#6900 - Actions page

Closes #7441

## Detailed Description of the Pull Request / Additional comments
The important thing here is to remember that we're shifting our philosophy of how to interact/represent actions. Prior to this, the actions arrays in the JSON would be deserialized twice: once for key bindings, and again for commands. By thinking of every entry in the relevant JSON as a `Command`, we can remove a lot of the context switching between working with a key binding vs a command palette item.

#9543 allows us to make that shift. Given the work in that PR, we can now deserialize all of the relevant information from each JSON action item. This allows us to simplify `ActionMap::FromJson` to simply iterate over each JSON action item, deserialize it, and add it to our `ActionMap`.

Internally, our `ActionMap` operates as discussed in #9428 by maintaining a `_KeyMap` that points to an action ID, and using that action ID to retrieve the `Command` from the `_ActionMap`. Adding actions to the `ActionMap` automatically accounts for name/key-chord collisions. A `NameMap` can be constructed when requested; this is for the Command Palette.

Querying the `ActionMap` is fairly straightforward. Helper functions were needed to be able to distinguish an explicit unbinding vs the command not being found in the current layer. Internally, we store explicitly unbound names/key-chords as `ShortcutAction::Invalid` commands. However, we return `nullptr` when a query points to an unbound command. This is done to hide this complexity away from any caller.

The command palette still needs special handling for nested and iterable commands. Thankfully, the expansion of iterable commands is performed on an `IMapView`, so we can just expose `NameMap` as a consolidation of `ActionMap`'s `NameMap` with its parents. The same can be said for exposing key chords in nested commands.

## Validation Steps Performed

All local tests pass.

[Spec] Settings Model - Actions (#9428)
This spec covers the settings model work required to create the Actions page in the settings UI (designed in #9427). 

Overall, the idea is to promote `Command` to include the actual `KeyChord`, then introduce an `ActionMap` that handles all of the responsibilities of `KeyMapping` and more (as well as general action management).

Fix TerminalControl crash on exit (#10031)
## Summary of the Pull Request

ControlCore's _renderer (IRenderTarget) is allocated as std::unique_ptr,
but is given to Terminal::CreateFromSettings as a reference.
ControlCore::Close deallocates the _renderer, but if ThrottledFuncs
are still scheduled to call ControlCore::UpdatePatternLocations
it'll cause Terminal::UpdatePatterns to be called, which in turn ends up
accessing the deallocated IRenderTarget reference and lead to a crash.

A proper solution with shared pointers is nontrivial and should be
attempted at a later point in time. This solution moves the teardown of
the _renderer into ControlCore::~ControlCore, where we can be certain
that no further strong references are held by ThrottledFuncs.

## PR Checklist

* [x] I work here
* [x] Tests added/passed

The crash is a race condition and inherently hard to reproduce.

Add globalSummon action (#9854)
Adds support for two new actions:
* `globalSummon`, which can be used to activate a window using a _global_ (READ: OS-level) hotkey.
  - accepts an optional `name` argument. When provided, this will attempt to summon with the given name. When omitted, we'll try to summon the most recent window.
* `quakeMode` which is `globalSummon` for the `_quake` window.

These actions are stored in the actions array, but are read by the `WindowsTerminal` level and bound to the OS in `IslandWindow`. The monarch registers for these keybindings with the OS. When one is pressed, the monarch will recieve a `WM_HOTKEY` message. It'll use that to look up the corresponding action args. It'll use those to try and summon the right window.

Split TermControl into a Core, Interactivity, and Control layer (#9820)
## Summary of the Pull Request

Brace yourselves, it's finally here. This PR does the dirty work of splitting the monolithic `TermControl` into three components. These components are: 

* `ControlCore`: This encapsulates the `Terminal` instance, the `DxEngine` and `Renderer`, and the `Connection`. This is intended to everything that someone might need to stand up a terminal instance in a control, but without any regard for how the UX works.
* `ControlInteractivity`: This is a wrapper for the `ControlCore`, which holds the logic for things like double-click, right click copy/paste, selection, etc. This is intended to be a UI framework-independent abstraction. The methods this layer exposes can be called the same from both the WinUI TermControl and the WPF control.
* `TermControl`: This is the UWP control. It's got a Core and Interactivity inside it, which it uses for the actual logic of the terminal itself. TermControl's main responsibility is now 

By splitting into smaller pieces, it will enable us to
* write unit tests for the `Core` and `Interactivity` bits, which we desparately need
* Combine `ControlCore` and `ControlInteractivity` in an out-of-proc core process in the future, to enable tab tearout.

However, we're not doing that work quite yet. There's still lots of work to be done to enable that, thought this is likely the biggest portion.

Ideally, this would just be methods moved wholesale from one file to another. Unfortunately, there are a bunch of cases where that didn't work as well as expected. Especially when trying to better enforce the boundary between the classes. 

We've got a couple tests here that I've added. These are partially examples, and partially things I ran into while implementing this. A bunch of things from #7001 can go in now that we have this.

This PR is gonna be a huge pain to review - 38 files with 3,730 additions and 1,661 deletions is nothing to scoff at. It will also conflict 100% with anything that's targeting `TermControl`. I'm hoping we can review this over the course of the next week and just be done with it, and leave plenty of runway for 1.9 bugs in post.

## Detailed Description of the Pull Request / Additional comments

* I don't love the names `ControlCore` and `ControlInteractivity`. Open to other names.
* I added a `ICoreState` interface for "properties that come from the `ControlCore`, but consumers of the `TermControl` need to know". In the future, these will all need to be handled specially, because they might involve an RPC call to retrieve the info from the core (or cache it) in the window process.
* I've added more `EventArgs` to make more events proper `TypedEvent`s.
* I've changed how the TerminalApp layer requests updated TaskbarProgress state. It doesn't need to pump TermControl to raise a new event anymore.
* ~~Something that snuck into this branch in the very long history is the switch to `DCompositionCreateSurfaceHandle` for the `DxEngine`. @miniksa wrote this originally in 30b8335, I'm just finally committing it here. We'll need that in the future for the out-of-proc stuff.~~
  * I reverted this in c113b65d9. We can revert _that_ commit when we want to come back to it.
* I've changed the acrylic handler a decent amount. But added tests!
* All the `ThrottledFunc` things are left in `TermControl`. Some might be able to move down into core/interactivity, but once we figure out how to use a different kind of Dispatcher (because a UI thread won't necessarily exist for those components).
* I've undoubtably messed up the merging of the locking around the appearance config stuff recently

Make the window name _quake special (#9785)
## Summary of the Pull Request

This PR adds some special behavior to the window named "\_quake".
* When creating the quake window, it ignores "initialRows" and "initialCols" and opens on the top half of the monitor.
  - It uses `initialPosition` to determine which monitor this is
* It cannot be moved
* It can only be vertically resized on the bottom border.
* It's always in focus mode.
  - We should probably have an issue tracking "Allow showing tabs in focus mode"? Maybe?
  - This one element is maybe the one I'm least attached to

When renaming a window to "\_quake", it adopts all those behaviors as well. It does not exit focus mode when leaving QM, nor does it resize back. That seemed unnecessary.

Spec for Quake Mode (#9274)
### ⇒ [doc link](https://github.com/microsoft/terminal/blob/dev/migrie/s/653-quake-mode/doc/specs/%23653%20-%20Quake%20Mode/%23653%20-%20Quake%20Mode.md) ⇐

## Summary of the Pull Request

After reading through 114+ comments in #653 and related issues, I think I've finally wrapped my head around all the possible scenarios for quake mode. <!-- Speak now or forever hold your peace. --> This also includes "minimize to tray", because the two are a powerful combination. With the work already prototyped in [`dev/migrie/f/653-QUAKE-MODE`](https://github.com/microsoft/terminal/tree/dev/migrie/f/653-QUAKE-MODE), [I'm starting to believe](https://j.gifs.com/58vKNx.gif) that we could actually land this in 2.0.


### Abstract

> Many existing terminals support a feature whereby a user can press a keybinding
> anywhere in the OS, and summon their terminal application. Oftentimes the act of
> summoning this window is accompanied by a "dropdown" animation, where the window
> slides in to view from the top of the screen. This global summon action is often
> referred to as "quake mode", a reference to the videogame Quake who's console
> slid in from the top.
> 
> This spec addresses both of the following two issues:
> * "Quake Mode" ([#653])
> * "Minimize to tray" ([#5727])

Replace Windows.Storage.Pickers with Common File Dialogs (#9760)
Using Pickers from an elevated application yields an
ERROR_ACCESS_DENIED. Of course it does: it was designed for the modern
app platform.

Using the common dialog infrastructure has some downsides¹, but it
doesn't crash and is just as flexible.

I've added some fun templated functions that help us with the
complexity.

Fixes #8957

¹You've got to use raw COM, and it runs in-proc instead of out-of-proc.

Does what it says on the can.

This is a follow up to #9472. Now that we have a control .lib, we can add tests for it. 

Unfortunately, the `TermControl` itself is a horrible mess. So this new unittest lib is empty for now. I'm working on actual tests as a part of #6842, but this PR is here to keep the diffs smaller.

Also, apparently `server.vcxproj` had the wrong GUID in it.

dx: add support for inverting all types of cursor (#9665)
This commit introduces support for inverting all types of cursor.

To invert the display without re-rendering any text, we draw the cursor
into a command list and then compose the command list with the existing
renderer using the MASK_INVERT composition flag.

This wouldn't normally work with our renderer because there is no
_background_ color to invert in some cases (such as when acrylic is in
use.)

To work around that, we're taking advantage of @zadjii-msft's two-pass
cursor renderer.

To properly invert the cursor over a transparent background:
(Examples are given below for two cursor types, but this applies to all
of them.)

First, we'll draw a "backplate" in the user's requested background color
(with the alpha channel set to 0xFF). (`firstPass` == true)

    EMPTY BOX  FILLED BOX
    =====      =====
    =   =      =====
    =   =      =====
    =   =      =====
    =====      =====

Second, the glyph is drawn (outside of the cursor renderer).

    EMPTY BOX  FILLED BOX
    ==A==      ==A==
    =A A=      =A=A=
    AAAAA      AAAAA
    A   A      A===A
    A===A      A===A

Last, we'll draw the cursor again in all white and use that as the
*mask* for inverting the already-drawn pixels. (`firstPass` == false) (#
= mask, a = inverted A)

    EMPTY BOX  FILLED BOX
    ##a##      ##a##
    #A A#      #a#a#
    aAAAa      aaaaa
    a   a      a###a
    a###a      a###a

Auto-format our XAML files and enforce in CI (#9589)
This adds [`XamlStyler.Console`] to our solution, and calls it when we
format the code, to also format
our .xaml files. 
* `XamlStyler.Console` is a dotnet tool so it needs to be restored with
  `dotnet tool restore`
* I've added a set of rules to approximately follow [@cmaneu's XAML guidelines].
  Those guidelines also recommend things based on the code-behind, which
  this tool can't figure out, but also _don't matter that much_.
* There's an extra step to strip BOMs from the output, since Xaml Styler
  adds a BOM by default. Some had them before and others didn't. BOMs
  have been nothing but trouble though.

Add a Fuzzing configuration and a version of conhost that can be fuzzed (#9604)
This commit introduces a new build configuration, "Fuzzing", which
enables the new address sanitizer (shipped in VS 16.9) and code
coverage over the entire solution. Only a small subset of projects
(those comprising original conhost, right now) are selected to build in
this configuration, and even then only in Fuzzing|x64.

It also adds a fuzzing-adapted build of conhost, which makes no server
connections and handles no client applications. To do this, I've
replicated a bit of the console startup routine into fuzzmain.cpp and
made up some fake data. This is the bare minimum required to boot up
Win32 interactivity (or VT interactivity!) and pretend that a process
has connected.

If we don't pretend that a process has connected, "conhost" will exit
immediately. If we don't forge the process list, conhost will exit. If
we can't provide a server handle, we can't provide a "device comm".

Minor changes were necessary to server/host such that they would accept
a preexisting "device comm". We use this new behavior to provide a
"null" one that only hangs up threads and otherwise responds to requests
successfully.

This fuzzing-adapted build links LLVM's libFuzzer, which is an excellent
coverage-based fuzzer that will produce a corpus of inputs that exercise
unique codepaths. Eventually, we can use this to generate known-"good"
inputs for anything.

I've gone ahead and added a fuzz function that yeets bytes directly into
WriteCharsLegacy, which was the original reason I went down this path.

The implementation of LLVMFuzzerTestOneInput should be replaced with
whatever you want to fuzz.

Implement Default Terminal (#7489)
- Implements the default application behavior and handoff mechanisms
  between console and terminal. The inbox portion is done already. This
  adds the ability for our OpenConsole.exe to accept the incoming server
  connection from the Windows OS, stand up a PTY session, start the
  Windows Terminal as a listener for an incoming connection, and then
  send it the incoming PTY connection for it to launch a tab.
- The tab is launched with default settings at the moment.
- You must configure the default application using the `conhost.exe`
  propsheet or with the registry keys. Finishing the setting inside
  Windows Terminal will be a todo after this is complete. The OS
  Settings panel work to surface this setting is a dependency delivered
  by another team and you will not see it here.

## Validation Steps Performed
- [x] Manual adjust of registry keys to the delegation conhost/terminal
  behavior
- [x] Adjustment of the delegation options with the propsheet
- [x] Launching things from the run box manually and watching them show
  in Terminal
- [x] Launching things from shortcuts and watching them show in the
  Terminal   

Documentation on how it works will be a TODO post completion in #9462

Create settings/tasks definitions for VScode builds and registration (#9297)
I wanted to start using VScode. It wasn't easy. I wrote some tasks that allow us to build the various flavors of OpenConsole and Windows Terminal from one of the tasks. I also wrote a task that allows registration of the loose Windows Terminal package and a shortcut one to launch it. 

Also it was grinding away at its own Intellisense forever because it was indexing obj, bin, packages, etc. I excluded those.

Things should be easier now for folks in general. I expect we'll make more task types in the future.

Add support for the windowingBehavior setting (#9118)
Adds support for the `windowingBehavior` global setting. This setting
controls how mutiple instances of `wt` behave in the absence of the `-w`
parameter. This setting has three values:
* `"useNew"`: (default) Multiple `wt` invocations (without the `-w`
  param) always create new windows. 
* `"useAnyExisting"`: When starting a new `wt`, we'll instead default to
  any existing windows. `wt -w -1` will still create new windows. 
* `"useExisting"`: Similar to `useAnyExisting`, but limits to
  windows on the current desktop. 

The IVirtualDesktopManager interface is _very_ limited. Hence why we
have to track the HWNDs manually, and ask if they're on the current
desktop.

Add support for double-width/double-height lines in conhost (#8664)
This PR adds support for the VT line rendition attributes, which allow
for double-width and double-height line renditions. These renditions are
enabled with the `DECDWL` (double-width line) and `DECDHL`
(double-height line) escape sequences. Both reset to the default
rendition with the `DECSWL` (single-width line) escape sequence. For now
this functionality is only supported by the GDI renderer in conhost.

There are a lot of changes, so this is just a general overview of the
main areas affected.

Previously it was safe to assume that the screen had a fixed width, at
least for a given point in time. But now we need to deal with the
possibility of different lines have different widths, so all the
functions that are constrained by the right border (text wrapping,
cursor movement operations, and sequences like `EL` and `ICH`) now need
to lookup the width of the active line in order to behave correctly.

Similarly it used to be safe to assume that buffer and screen
coordinates were the same thing, but that is no longer true. Lots of
places now need to translate back and forth between coordinate systems
dependent on the line rendition. This includes clipboard handling, the
conhost color selection and search, accessibility location tracking and
screen reading, IME editor positioning, "snapping" the viewport, and of
course all the rendering calculations.

For the rendering itself, I've had to introduce a new
`PrepareLineTransform` method that the render engines can use to setup
the necessary transform matrix for a given line rendition. This is also
now used to handle the horizontal viewport offset, since that could no
longer be achieved just by changing the target coordinates (on a double
width line, the viewport offset may be halfway through a character).

I've also had to change the renderer's existing `InvalidateCursor`
method to take a `SMALL_RECT` rather than a `COORD`, to allow for the
cursor being a variable width. Technically this was already a problem,
because the cursor could occupy two screen cells when over a
double-width character, but now it can be anything between one and four
screen cells (e.g. a double-width character on the double-width line).

In terms of architectural changes, there is now a new `lineRendition`
field in the `ROW` class that keeps track of the line rendition for each
row, and several new methods in the `ROW` and `TextBuffer` classes for
manipulating that state. This includes a few helper methods for handling
the various issues discussed above, e.g. position clamping and
translating between coordinate systems.

## Validation Steps Performed

I've manually confirmed all the double-width and double-height tests in
_Vttest_ are now working as expected, and the _VT100 Torture Test_ now
renders correctly (at least the line rendition aspects). I've also got
my own test scripts that check many of the line rendition boundary cases
and have confirmed that those are now passing.

I've manually tested as many areas of the conhost UI that I could think
of, that might be affected by line rendition, including things like
searching, selection, copying, and color highlighting. For
accessibility, I've confirmed that the _Magnifier_ and _Narrator_
correctly handle double-width lines. And I've also tested the Japanese
IME, which while not perfect, is at least useable.

Add support for XTPUSHSGR / XTPOPSGR (#1978)
Implement the `XTPUSHSGR` and `XTPOPSGR` control sequences (see #1796).

This change adds a new pair of methods to `ITermDispatch`:
`PushGraphicsRendition` and `PopGraphicsRendition`, and then plumbs the
change through `AdaptDispatch`, `TerminalDispatch`, `ITerminalApi` and
`TerminalApi`.

The stack logic is encapsulated in the `SgrStack` class, to allow it to
be reused between the two APIs (`AdaptDispatch` and `TerminalDispatch`).

Like xterm, only ten levels of nesting are supported.

The stack is implemented as a "ring stack": if you push when the stack
is full, the bottom of the stack will be dropped to make room.

Partial pushes (see the description of `XTPUSHSGR` in Issue #1796) are
implemented per xterm spec.

Add support for running a commandline in another WT window (#8898)
## Summary of the Pull Request

**If you're reading this PR and haven't signed off on #8135, go there first.**

![window-management-000](https://user-images.githubusercontent.com/18356694/103932910-25199380-50e8-11eb-97e3-594a31da62d2.gif)

This provides the basic parts of the implementation of #4472. Namely:
* We add support for the `--window,-w <window-id>` argument to `wt.exe`, to allow a commandline to be given to another window.
    * If `window-id` is `0`, run the given commands in _the current window_.
    * If `window-id` is a negative number, run the commands in a _new_ Terminal window.
    * If `window-id` is the ID of an existing window, then run the commandline in that window.
    * If `window-id` is _not_ the ID of an existing window, create a new window. That window will be assigned the ID provided in the commandline. The provided subcommands will be run in that new window.
    * If `window-id` is omitted, then create a new window.

* [ ] We don't support window glomming by default, or a setting to configure what happens when `-w` is omitted. I thought it best to lay the groundwork first, then come back to that.
* [ ] `-w 0` currently just uses the "last activated" window, not "the current". There's more follow-up work to try and smartly find the actual window we're being called from.
* [ ] Basically anything else that's listed in projects/5.

I'm cutting this PR where it currently is, because this is already a huge PR. I believe the remaining tasks will all be easier to land, once this is in. 

## Validation Steps Performed

I've been creating windows, and closing them, and running cmdlines for a while now. I'm gonna keep doing that while the PR is open, till no bugs remain.

# TODOs
* [x] There are a bunch of `GetID`, `GetPID` calls that aren't try/caught 😬 
  -  [x] `Monarch.cpp`
  -  [x] `Peasant.cpp`
  -  [x] `WindowManager.cpp`
  -  [x] `AppHost.cpp`
* [x] If the monarch gets hung, then _you can't launch any Terminals_ 😨 We should handle this gracefully.
  - Proposed idea: give the Monarch some time to respond to a proposal for a commandline. If there's no response in that timeframe, this window is now a _hermit_, outside of society entirely. It can't be elected Monarch. It can't receive command lines. It has no ID.  
  	- Could we gracefully recover from such a state? maybe, probably not though.
    -  Same deal if a peasant hangs, it could end up hanging the monarch, right? Like if you do `wt -w 2`, and `2` is hung, then does the monarch get hung waiting on the hung peasant?
  - After talking with @miniksa, **we're gonna punt this from the initial implementation**. If people legit hit this in the wild, we'll fix it then.

Fixed #5205: Ctrl+Alt+2 doesn't send ^[^@ (#5272)
## Summary of the Pull Request

Fixes #5205, by replacing another use of `MapVirtualKeyW` with `ToUnicodeEx`.
The latter just seems to be much more consistent at translating key combinations in general.
In this particular case though it fixes the issue, because there's no differentiation in `MapVirtualKeyW` for whether it failed to return a character (`'\0'`) or succeeded in turning `^@` into `'\0'`.
`ToUnicodeEx` on the other hand returns the success state separately from the translated character.

## Detailed Description of the Pull Request / Additional comments

This PR changes the behavior of the `Ctrl+Alt+Key` handling slightly:
⚠️ `ToUnicodeEx` returns unshifted characters. ⚠️
For instance `Ctrl+Alt+a` is now turned into `^[^a`. Due to how ASCII works this is essentially the same though because `'A' & 0b11111` and `'a' & 0b11111` are the same.

## Validation Steps Performed

* Run `showkey -a`
* Ensured `Ctrl+Alt+Space` as well as `Ctrl+Alt+Shift+2` are turned into `^[^@`
* Ensured other, random `Ctrl+Alt+Key` combination behave identical to the current master
