This implements command line matching for `CascadiaSettings::GetProfileForArgs`.
The command lines for all user profiles are resolved to absolute file paths,
argument quotes are standardized ("canonicalized") and the results are cached.
When `GetProfileForArgs` is called with a Commandline() value, we "canonicalize"
the argument as well and find the profile that is the longest prefix.
If none could be found the default profile is returned.

In #11180 we made `opacity` independent from `useAcrylic`. We also changed the mouse wheel behavior to only change opacity, and not mess with acrylic.
However, on Windows 10, vintage opacity doesn't work at all. So there, we still need to manually enable acrylic when the user requests opacity.

SUI changes in action:
It's possible that we're about to be started, _before_
our paired connection is started. Both will get Start()'ed when
their owning TermControl is finally laid out. However, if we're
started first, then we'll immediately start printing to the other
control as well, which might not have initialized yet. If we do
that, we'll explode.
Instead, wait here until the other connection is started too,
before actually starting the connection to the client app. This
will ensure both controls are initialized before the client app
is.
Fixes#11282
Tested: Opened about 100 debug taps. They all worked. :shipit:
`CascadiaSettings` is default constructed when human readable error messages are
returned. Even in such cases we need to ensure that all fields are properly
initialized, as a caller might decide to call a `GlobalSettings` getter.
Thus a crash occurred whenever a user was hot-reloading their settings file with
invalid JSON as other code then tried to compare the `GlobalSettings()`.

WinUI/XAML requires the `SelectedItem` to be member of the list of
`ItemsSource`. `CascadiaSettings::DefaultTerminals()` is such an `ItemsSource`
and is called every time the launch settings page is visited.
It calls `DefaultTerminal::Available()` which in turn calls `Refresh()`.
While the `SelectedItem` was cached in `CascadiaSettings`, the value of
`DefaultTerminals()` wasn't. Thus every time the page was visited, it refreshed
the `ItemsSource` list without invalidating the current `SelectedItem`.
This commit prevents such accidental mishaps from occurring in the future,
by moving the responsibility of caching solely to the `CascadiaSettings` class.

## Summary of the Pull Request
Fixes two issues related to SUI's Actions page:
1. Crash when adding an action and setting key chord to one that is already taken
- **Cause**: the new key binding that was introduced with the "Add new" button appears in `_KeyBindingList` that we're iterating over. This has no `CurrentKeys()`, resulting in a null pointer exception.
- **Fix**: null-check it
2. There's an action that appears as being nameless in the dropdown
- **Cause**: The culprit seems to be `MultipleActions`. We would register it, but it wouldn't have a name, so it would appear as a nameless option.
- **Fix**: if it has no name, don't register it. This is also future-proof in that any new nameless actions won't be automatically added.

I've validated that a string makes Windows Terminal complain it's a string and not a number, and that a number works as expected, and that the default is indeed zero.
This commit introduces a number of poor abstractions to split
`SettingsLoader::_parse` into `_parse` for content in the format of the user's
settings.json and `_parseFragment` which is specialized for fragment files.
The latter suppresses exceptions and supports the "updates" key for profiles.

## Summary of the Pull Request
The deadlock was caused by `ScreenInfoUiaProviderBase::GetSelection()` calling `TermControlUiaProvider::GetSelectionRange` (both of which attempted to lock the console). This PR removes the lock and initialization check from `TermControlUiaProvider`. It is no longer necessary because the only one that calls it is `SIUPB::GetSelection()`.
Additionally, this adds some code that was useful in debugging this race condition. That should help us figure out any locking issues that may come up in the future.

Similar to `vswhere -latest`, show only the latest Visual Studio command prompts / developer PowerShell. This was tested by deleting the local package state and testing against fresh state with both VS2019 and VS2022 Preview installed, and indeed VS2022 Preview (both cmd and powershell) show. The other profiles were generated but hidden by default.

## Detailed Description of the Pull Request / Additional comments
The sort algorithm is the same basic algorithm I used in https://github.com/microsoft/vswhere. It sorts first by installation version with a secondary sort based on the install date in case the installation versions are the same.
## Validation Steps Performed
With both VS2019 and VS2022 Preview installed, I made sure the initial state was expected, and tried different combinations of hiding and unhiding generated entries, and restarted Terminal to make sure my settings "stuck".
All these controls didn't have `Name`s assigned, and Accessibility Insights doesn't like that. Their parents did, but the actual focusable elements themselves didn't. So I've just taken the nearby headers for these things and slapped them in as the Automation names for these controls.
I verified that each of these automated tests in Accessibility Insights pass again.
* Will do the thing to #11155 but we need confirmation before that can be closed.
DESPITE the fact that there's a `Background()` API that we
could just call like:
```c++
TabViewItem().Background(deselectedTabBrush);
```
We actually can't, because it will make the part of the tab that
doesn't contain the text totally transparent to hit tests. So we
actually _do_ still need to set `TabViewItemHeaderBackground` manually.

## Validation Steps Performed
I've manually confirmed that all the different gridlines are still rendering correctly in both the GDI and DX renderers.
This logic was seemingly redundant. There's two cases I'm looking at here:
#### Case 1
```jsonc
"defaults":
{
"opacity": 35
},
"list":
[
{
"commandline": "cmd.exe",
"name": "Command Prompt"
},
```
In this case, we wouldn't set the `TerminalSettings` Opacity to .35, we'd set it to 1.0, because the profile didn't have an `opactity`.
#### Case 2
```jsonc
"defaults":
{
"useAcrylic": true
},
"list":
[
{
"commandline": "cmd.exe",
"name": "Command Prompt"
},
```
In this case we still want to have an acrylic effect. Previously, we'd default this effect to 50% opaque. I'm not sure that we can actually get that anymore. BUT it turns out, we _can_ have 100% opacity and HostBackdropAcrylic. It is very subtle, but is maybe something we should be allowing anyways. It kinda looks like:

This commit adds the ability to interact with subtrees of panes.
Have you ever thought that you don't have enough regression testing to
do? Boy do I have the PR for you! This breaks all kinds of assumptions
about what is or is not focused, largely complicated by the fact that a
pane is not a proper control. I did my best to cover as many cases as I
could, but I wouldn't be surprised if there are some things broken that
I am unaware of.
Done:
- Add `parent` and `child` movement directions to move up and down the
tree respectively
- When a parent pane is selected it will have borders all around it in
addition to any borders the children have.
- Fix focus, swap, split, zoom, toggle orientation, resize, and move to
all handle interacting with more than one pane.
- Similarly the actions for font size changing, closing, read-only, clearing
buffer, and changing color scheme will distribute to all children.
- This technically leaves control focus on the original control in the
focused subtree because panes aren't proper controls themselves. This
is also used to make sure we go back down the same path with the
`child` movement.
- You can zoom a parent pane, and click between different zoomed
sub-panes and it won't unzoom you until you use moveFocus or another
action. This wasn't explicitly programmed behavior so it is probably
buggy (I've quashed a couple at least). It is a natural consequence of
showing multiple terminals and allowing you to focus a terminal and a
parent separately, since changing the active pane directly does not
unzoom. This also means there can be a disconnect between what pane is
zoomed and what pane is active.
## Validation Steps Performed
Tested focus movement, swapping, moving panes, and zooming.

## Detailed Description of the Pull Request / Additional comments
Rough changelog:
Normally saving is triggered to occur every 30s, or sooner if a window is created/closed. The existing behavior of saving on last close is maintained to bypass that throttling. The automatic saving allows for crash recovery. Additionally all window layouts will be saved upon taking the `quit` action.
For loading we will check if we are the first window, that there are any saved layouts, and if the setting is enabled, and then depending on if we were given command line args or startup actions.
- create a new window for each saved layout, or
- take the first layout for our self and then a new window for each other layout.
This also saves the layout when the quit action is taken.
Misc changes
- A -s,--saved argument was added to the command line to facilitate opening all of the windows with the right settings. This also means that while a terminal session is running you can do wt -s idx to open a copy of window idx. There isn't a stable ordering of which idx each window gets saved as (it is whatever the iteration order of _peasants is), so it is just a cute hack for now.
- All position calculation has been moved up to AppHost this does mean we need to awkwardly pass around positions in a couple of unexpected places, but no solution was perfect.
- Renamed "Open tabs from a previous session" to "Open windows from a previous session". (not reflected in video below)
- Now save runtime tab color and window names
- Only enabled for non-elevated windows
- Add some change tracking to ApplicationState
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
`SettingsLoader::_parse` used to skip profiles which didn't have either a "guid"
or "name" field, due to #9962. This is however wrong for fragment loading, as
fragments can alternatively use an "updates" field instead of guid/name.
`SettingsLoader::_parse` was updated to allow profiles with this alternative
field during fragment loading.

## Summary of the Pull Request
This introduces a new TIL class that is equivalent in functionality to a `std::bitset`, but where the positions in the bitset are enum values. It also has a few additional methods allowing for setting and testing multiple positions at the same time. The idea is that this class could be used in place of the `WI_SetFlag` and `WI_IsFlagSet` macros when working with sets of flags.

## Validation Steps Performed
I've added a few unit tests that verify the behaviour of all the new methods that aren't part of `std::bitset`. I've also tried it out as a replacement for the `GridLines` enum used in the renderer, and confirmed that it has all the functionality needed to replace that cleanly.
This commit fixes layering of fragment profiles without an update key.
The previous CascadiaSettings deserializer first assembled all builtin
profiles and only then parsed the user's settings.json file.
This meant that even though fragment profiles were added to `_allProfiles`
unconditionally, they did get layered properly with user profiles regardless,
as user profiles were always properly layered.
The new CascadiaSettings approach since 168d28b was a direct translation of this
approach but this is incorrect: As the new approach reads user profiles first,
all inbox profiles, including fragments, must equally use proper layering,
instead of adding profiles unconditionally.
While this commit fixes the bug it maintains a regression:
Duplicate fragment profile GUIDs will not be detected and instead fragments with
identical GUID will all be added as parents to a single user profile.
I considered to fix this regression, but felt that this new behavior is better
than the old one, since a user often can't directly control installed fragments,
and is unlikely to occur in practice. This simplifies the implementation.

This was broken in two places - when constructing the command-line in the shell extension and in `NewTerminalArgs::ToCommandline()`.
Both places now invoke a shared method to escape the command-line arguments that require it.

## References
Closes#11135#10971 & #11042
## Detailed Description of the Pull Request / Additional comments
Originally, I tried applying this heuristic to all the `RuntimeClassInitialize` on `UiaTextRangeBase` with the philosophy of "a range pointing to an invalid buffer is invalid itself", but that caused a regression on [MSFT 33353327](https://microsoft.visualstudio.com/OS/_workitems/edit/33353327).
`IUiaData` also has `GetTextBuffer()` return a `TextBuffer&`, which cannot be checked for nullness. Instead, I decided to add a function to `IUiaData` that checks if we have a valid state. Since this is shared with Conhost and Conhost doesn't have this issue, I simply make that function say that it's always in a valid state.

Implements the following keyboard selection non-configurable key bindings:
- shift+arrow --> move endpoint by character
- ctrl+shift+left/right --> move endpoint by word
- shift+home/end --> move to beginning/end of line
- ctrl+shift+home/end --> move to beginning/end of buffer
This was purposefully done in the ControlCore layer to make keyboard selection an innate part of how the terminal functions (aka a shared component across terminal consumers).

## Detailed Description of the Pull Request / Additional comment
The most relevant section is `TerminalSelection.cpp`, where we define how each movement operates. It's basically a giant embedded switch-case statement. We leverage a lot of the work done in a11y to perform the movements.
## Validation Steps Performed
- General cases:
- test all of the key bindings added
- Corner cases:
- `char`: wide glyph support
- `word`: move towards, away, and across the selection pivot
- automatically scroll viewport
- ESC (and other key combos) are still clearing the selection properly

to do it a while ago. This one is rough, but the whole changelog process
is pretty rough.
This script takes multiple revision ranges and produces something that
looks like a rough untranslated changelog, with indicators for how many
of the provided ranges had the same change (deduplicated by title.)
I use a process like this to build the Stable and Preview release notes
out of a set of revision ranges.
This introduces a spec for keyboard selection. This enables the user to create and update a selection without the use of a mouse or stylus.
