The UIA Provider now scrolls the viewport when necessary. This just fills in the missing virtual function in Terminal to have the same behavior as what it does in ConHost.
* [X] Closes#2361
* [X] CLA signed.
`ChangeViewport` is now a virtual function at the `ScreenInfoUiaProvider` layer to have access to the TermControl.
In ConHost, we pass this call up to the WindowUiaProvider layer. In Terminal, we don't need to do that because the concept of updating the viewport is handled at the TermControl layer. So we just call that function and _voila_!
## Summary of the Pull Request

## Detailed Description of the Pull Request / Additional comments
There are two ways scroll can happen:
- the user scrolls using the scroll bar and the `Terminal` is notified
- the `Terminal` changed the viewport and the scroll bar is updated to reflect the change
The code to notify the `Terminal` that the user scrolled is in the event handler for when the scroll bar's value changes. However this poses a problem because it means that when the `Terminal` changes the viewport, the scroll bar is updated so it would then also notify the `Terminal` that the scroll changed. But it already knows because it's coming from itself!
To fix this, the `TermControl` class had a member called `_lastScrollOffset` that would be set when the `Terminal` decides to change the viewport so that the event handler for the scroll bar could check the new scroll value against `_lastScrollOffset` and if it matches, then everything is fine and there is nothing to update.
This is what happens when the `Terminal` changes the viewport:
1. set `_lastScrollOffset`
2. dispatch job on the UI thread: update the scrollbar which is going to call the event handler which is going to check for `_lastScrollOffset` and clear it
There are two bugs introduced by this approach:
1. (I am not sure about this.) The dispatcher appears to store jobs in a LIFO stack so it sometimes reorders the "update the scrollbar" jobs when there are too many. When I run `1..10000` on PowerShell, then I get this from the event handler (format: `_lastScrollOffset newValue`):
```
8988 8988
8989 8989
8990 8990
8992 8991
8993 8992
...
9001 8997
9001 8998
9001 8999
9001 9000
9001 9001
9001 8985
9001 8968
9001 8953
...
9001 7242
9001 7226
9001 7210
```
This causes the following issues:
1. `_lastScrollOffset` wouldn't be reset because it wouldn't be equal to the current scroll bar value (see example above) so the next scrolls wouldn't do anything as the event handler would still be waiting for an event with the good scroll bar value which would never happen because it happened earlier
2. the `TermControl` would notify the `Terminal` about its own scroll
2. If the `Terminal` didn't actually changed its viewport but still called the `TermControl::_TerminalScrollPositionChanged` method, then it would set the `_lastScrollOffset` member as usual but the scroll bar value change event handler would not be called because it is only called when the value actually changes so the `_lastScrollOffset` member wouldn't be cleared and subsequent scroll bar value change events would be ignored because again the event handler would still be waiting for an event with the good scroll bar value which would never happen. This is actually the reason for #1494: when the window is resized, the `Terminal` will call `TermControl::_TerminalScrollPositionChanged` even if the scroll position didn't actually change (444de5b166/src/cascadia/TerminalCore/Terminal.cpp (L183)). Maybe this should also be fixed in another PR?
I replaced `_lastScrollOffset` by a flag `_isTerminalInitiatedScroll`. I set the flag just before and unset it just after the terminal changes the scrollbar on the UI thread to eliminate the race conditions and the bug when the scroll bar's value doesn't actually change.
Other changes:
- I also fixed a potential bug where if the user scrolls just after the terminal updates the viewport, it would en up ignoring the user scroll. To do this, when the user scrolls, I cancel any update with `_willUpdateScrollBarToMatchViewport`.
- I also removed the original `ScrollViewport` method because it was not used anywhere and I think it can potentially create confusion (and therefore bugs) because this method updates the viewport but not the scroll bar unlike `KeyboardScrollViewport` which functions as you would expect. I then renamed `KeyboardScrollViewport` into `ScrollViewport`. So, now, there is only one method to scroll the viewport from the `TermControl`. Please, tell me if this shouldn't be in this PR.
- I also removed `_terminal->UserScrollViewport(viewTop);` in the `KeyboardScrollViewport` method because it will be updated later anyways in the scroll bar's value change event handler because of the `_scrollBar.Value(viewTop);`.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
I tested manually by doing this:
- For bug 1:
1. Start the terminal
2. Run the `1..30000` command in PowerShell and wait for it to end (maybe more if you have a fast computer?)
3. Hold left click on the scrollbar slider and start moving it
- For bug 2:
1. Start the terminal
2. Run the `1..100` command in PowerShell and wait for it to end
3. Resize the window horizontally
4. Hold left click on the scrollbar slider and start moving it
Without this patch, the viewport doesn't update.
With the patch, the viewport updates correctly.

Closes#4294
Moved `FindText` to `UiaTextRangeBase`. Now that Search is a shared component (thanks #3279), I can just reuse it basically as-is.
#3279 - Make Search a shared component
#4018 - UiaTextRange Refactor
I removed it from the two different kinds of UiaTextRange and put it in the base class.
I needed a very minor change to ensure we convert from an inclusive end (from Search) to an exclusive end (in UTR).
Worked with `FindText` was globally messed with in windows.h. So we had to do a few weird things there (thanks Michael).
No need for additional tests because it _literally_ just sets up a Searcher and calls it.
## Summary of the Pull Request
This pull request is intended to achieve the following goals...
1) reduce duplicate code
2) remove static functions
3) improve readability
4) improve reliability
5) improve code-coverage for testing
6) establish functioning text buffer navigation in Narrator and NVDA
This also required a change to the wrapper class `XamlUiaTextRange` that has been causing issues with Narrator and NVDA.
See below for additional context.

## Detailed Description of the Pull Request / Additional comments
### UiaTextRange
- converted endpoints into the COORD system in the TextBuffer coordinate space
- `start` is inclusive, `end` is exclusive. A degenerate range is when start == end.
- all functions are no longer static
- `MoveByUnit()` functions now rely on `MoveEndpointByUnit()` functions
- removed unnecessary typedefs like `Endpoint`, `ScreenInfoRow`, etc..
- relied more heavily on existing functionality from `TextBuffer` and `Viewport`
### XamlUiaTextRange
- `GetAttributeValue()` must return a special HRESULT that signifies that the requested attribute is not supported. This was the cause of a number of inconsistencies between Narrator and NVDA.
- `FindText()` should return `nullptr` if nothing was found. #4373 properly fixes this functionality now that Search is a shared module
### TextBuffer
- Word navigation functionality is entirely in `TextBuffer` for proper abstraction
- a total of 6 functions are now dedicated to word navigation to get a good understanding of the differences between a "word" in Accessibility and a "word" in selection
As an example, consider a buffer with this text in it:
" word other "
In selection, a "word" is defined as the range between two delimiters, so the words in the example include [" ", "word", " ", "other", " "].
In accessibility , a "word" includes the delimiters after a range of readable characters, so the words in the example include ["word ", "other "].
Additionally, accessibility word navigation must be able to detect if it is on the first or last word. This resulted in a slight variant of word navigation functions that return a boolean instead of a COORD.
Ideally, these functions can be consolidated, but that is too risky for a PR of this size as it can have an effect on selection.
### Viewport
- the concept of `EndExclusive` is added. This is used by UiaTextRange's `end` anchor as it is exclusive. To signify that the last character in the buffer is included in this buffer, `end` must be one past the end of the buffer. This is `EndExclusive`
- Since many functions check if the given `COORD` is in bounds, a flag must be set to allow `EndExclusive` as a valid `COORD` that is in bounds.
### Testing
- word navigation testing relies more heavily on TextBuffer tests
- additional testing was created for non-movement focused functions of UiaTextRange
- The results have been compared to Microsoft Word and some have been verified by UiAutomation/Narrator contacts as expected results.
## Validation Steps Performed
Tests pass
Narrator works
NVDA works
This PR addresses the following two issues:
#4203: If a selection is active, a <kbd>shift</kbd>-LeftClick will set the SelectionEnd to where the pointer is.
#3911: Currently, any keypress will clear selection, and will pass through to the terminal. This PR will make it so that if a selection is active, _any_ keypress will clear the selection and then any keypress _except_ <kbd>esc</kbd> will pass through to the terminal.

We were overriding the button foreground and the placeholder foreground using our
own custom resource names. They didn't exist in HC.
Instead of making them exist in HC, I made us use and override the real resource
names. Those ones have HC colors defined by the platform!

Okay it was a little more complicated than that. I had `IslandWindow` handle the drop, which then raises a generic event for `AppHost` to handle. `AppHost` handles this by writing the path as input to the terminal, traversing `AppLogic`, `TerminalPage` and finally landing in `TermControl`

## Detailed Description of the Pull Request / Additional comments
🛑 **STOP** 🛑 - have you read #3495 yet? If you haven't, go do that now.
This PR adds support for three initial sub-commands to the `wt.exe` application:
* `new-tab`: Used to create a new tab.
* `split-pane`: Used to create a new split.
* `focus-tab`: Moves focus to another tab.
These commands are largely POC to prove that the commandlines work. They're not totally finished, but they work well enough. Follow up work items will be filed to track adding support for additional parameters and subcommands
Important scenarios added:
* `wt -d .`: Open a new wt instance in the current working directory #878
* `wt -p <profile name>`: Create a wt instance running the given profile, to unblock #576, #1357, #2339
* `wt ; new-tab ; split-pane -V`: Launch the terminal with multiple tabs, splits, to unblock #756
## Validation Steps Performed
* Ran tests
* Played with it a bunch
This commit introduces a new recursive pane shutdown that will give all
controls under a tab a chance to clean up their state before beign
detached from the UI. It also reorders the call to LastTabClosed() so
that the application does not exit before the final connections are
terminated.
It also teaches TSFInputControl how to shut down to avoid a dramatic
platform bug.
Fixes#4159.
Fixes#4336.

## Detailed Description of the Pull Request / Additional comments
My thought pattern here was to minimally disturb the existing code where possible. So where I could, I converted existing functions into coroutine using functions (like in the [core example](https://github.com/microsoft/terminal/issues/3919#issue-536598706)). For ~the most part~ all instances, I used the format where [`this` is accessed safely within a locked scope](https://github.com/microsoft/terminal/issues/3919#issuecomment-564730620). Some function signatures were changed to take objects by value instead of reference, so the coroutines don't crash when the objects are accessed past their original lifetime. The [copy](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1132) and [paste](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1170) event handler entry points were originally set to a high priority; however, the WinRT coroutines don't appear to support a priority scheme so this priority setting was not preserved in the translation.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Compiles and runs, and for every event with a clear trigger repro, I triggered it to ensure crashes weren't introduced.
When user resizes window, snap the size to align with the character grid
(like e.g. putty, mintty and most unix terminals). Properly resolves
arbitrary pane configuration (even with different font sizes and
padding) trying to align each pane as close as possible.
It also fixes terminal minimum size enforcement which was not quite well
handled, especially with multiple panes.
This PR does not however try to keep the terminals aligned at other user
actions (e.g. font change or pane split). That is to be tracked by some
other activity.
Snapping is resolved in the pane tree, recursively, so it (hopefully)
works for any possible layout.
Along the way I had to clean up some things as so to make the resulting
code not so cumbersome:
1. Pane.cpp: Replaced _firstPercent and _secondPercent with single
_desiredSplitPosition to reduce invariants - these had to be kept in
sync so their sum always gives 1 (and were not really a percent). The
desired part refers to fact that since panes are aligned, there is
usually some deviation from that ratio.
2. Pane.cpp: Fixed _GetMinSize() - it was improperly accounting for
split direction
3. TerminalControl: Made dedicated member for padding instead of
reading it from a control itself. This is because the winrt property
functions turned out to be slow and this algorithm needs to access it
many times. I also cached scrollbar width for the same reason.
4. AppHost: Moved window to client size resolution to virtual method,
where IslandWindow and NonClientIslandWindow have their own
implementations (as opposite to pointer casting).
One problem with current implementation is I had to make a long call
chain from the window that requests snapping to the (root) pane that
implements it: IslandWindow -> AppHost's callback -> App ->
TerminalPage -> Tab -> Pane. I don't know if this can be done better.
## Validation Steps Performed
Spam split pane buttons, randomly change font sizes with ctrl+mouse
wheel and drag the window back and forth.
Closes#2834Closes#2277
The first argument to `NotifyTextChanged` incorrectly was `[0,0]`
instead of the length of the text to be removed from the
`CoreTextEditContext`.
Best source of documentation for `NotifyTextChanged`:
https://docs.microsoft.com/en-us/windows/uwp/design/input/custom-text-input#overriding-text-updates
FYI @DHowett-MSFT (just in case): C++/WinRT uses `winrt::param::hstring`
for string parameters which intelligently borrows strings. As such you
can simply pass a `std::wstring` to most WinRT methods without the need
of having to allocate an intermediate `hstring`. 🙂
## Validation Steps Performed
I followed the reproduction instructions of #3706 and #3745 and ensured
the issue doesn't happen anymore.
Closes#3645Closes#3706Closes#3745
The terminal will use the system setting to determine the number of lines to scroll at a time.
This can be overridden by adding rowsToScroll to app global settings file.
terminal will use the system setting if the app setting is 0, or not specified. No restart is needed to reflect setting changes in system or the settings file.
The default was hardcoded to 4 in the code with a todo comment. 1 works better on precision touchpads, where 4 scrolls too fast.

These functionalities are included in the search experience.
1. Search in Terminal text buffer.
2. Automatic wrap-around.
3. Search up or down switch by clicking different buttons.
4. Search case sensitively/insensitively by clicking a button. S. Move the search box to the top/bottom by clicking a button.
6. Close by clicking 'X'.
7. Open search by ctrl + F.
When the searchbox is open, the user could still interact with the terminal by clicking the terminal input area.
While I already have the search functionalities, currently there are still some known to-do works and I will keep updating my PR:
1. Optimize the search box UI, this includes:
1) Theme adaptation. The search box background and font color
should change according to the theme,
2) Add background. Currently the elements in search box are all
transparent. However, we need a background.
3) Move button should be highlighted once clicked.
2. Accessibility: search process should be able to performed without mouse. Once the search box is focused, the user should be able to navigate between all interactive elements on the searchbox using keyboard.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
To test:
1. checkout this branch.
2. Build the project.
3. Start Windows Terminal and press Ctrl+F
4. The search box should appear on the top right corner.

## Summary of the Pull Request
An asynchronous event handler capturing raw `this` in `TermControl` was causing an exception to be thrown when a scroll update event occurred after closing the active tab. This PR replaces all non-auto_revoke lambda captures in `TermControl` to capture (and validate) a `winrt::weak_ref` instead of using raw `this`.

## Detailed Description of the Pull Request / Additional comments
`TermControl` is already a WinRT type so no changes were required to enable the `winrt::weak_ref` functionality. There was only one strange change I had to make. In the destructor's helper function `Close`, I had to remove two calls to [`Stop`](https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.dispatchertimer.stop#Windows_UI_Xaml_DispatcherTimer_Stop) which were throwing under [some circumstances](https://github.com/microsoft/terminal/issues/2947#issuecomment-562914135). Fortunately, these calls don't appear to be critical, but definitely a spot to look into when reviewing this PR.
Beyond scrolling, any anomalous crash related to the following functionality while closing a tab or WT may be fixed by this PR:
- Settings updating
- Changing background color
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Before these changes I was able to consistently repro the issue in #2947. Now, I can no longer repro the issue.
Enables support for word navigation when using an automation client (i.e.: Narrator, etc...). Specifically, adds this functionality to the UiaTextRange class. The only delimiter used is whitespace because that's how words are separated in English.
# General "Word Movement" Expectations
The resulting text range should include any word break characters that are present at the end of the word, but before the start of the next word. (Source)
If you already are on a word, getting the "next word" means you skip the word you are on, and highlight the upcoming word appropriately. (similar idea when moving backwards)
# Word Expansion
Since word selection is supposed to detect word delimiters already, I figured I'd reuse that code. I moved it from TerminalCore to the TextBuffer.
Then I built on top of it by adding an optional additional parameter that decides if you want to include...
- the delimiter run when moving forward
- the character run when moving backwards
It defaults to false so that we don't have to care when using it in selection. But we change it to true when using it in our UiaTextRange
# UiaTextRange
The code is based on character movement. This allows us to actually work with boundary conditions.
The main thing to remember here is that each text range is recorded as a MoveState. The text range is most easily defined when you think about the start Endpoint and the end Endpoint. An Endpoint is just a linear 1-dimensional indexing of the text buffer. Examples:
- Endpoint 0 --> (0,0)
- Endpoint 79 --> (79,0) (when the buffer width is 80)
- Endpoint 80 -->(0,1) (when the buffer width is 80)
- When moving forward, the strategy is to focus on moving the end Endpoint. That way, we properly get the indexing for the "next" word (this also fixes a wrapping issue). Then, we update the start Endpoint. (This is reversed for moving backwards).
- When moving a specific Endpoint, we just have a few extra if statements to properly adjust for moving start vs end.
# Hooking it up
All we really had to do is add an enum. This part was super easy :)
I originally wanted the delimiters to be able to be defined. I'm not so sure about that anymore. Either way, I hardcoded our delimiter into a variable so if we ever want to expand on it or make that customizable, we just modify that variable.
# Defining your own word delimiters
- Import a word delimiter into the constructor of the ScreenInfoUiaProvider (SIUP)
- This defines a word delimiter for all the UiaTextRanges (UTR) created by in this context
- import a word delimiter into the UTR directly
- this provides more control over what a "word" is
- this can be useful if you have an idea of what text a particular UTR will encounter and you want to customize the word navigation for it (i.e consider adding / or \\ for file paths)
The default param of " " is scattered throughout because this is the word delimiter used in the English language.
## Summary of the Pull Request
The original PR had a few TODOs in it without issue numbers. IMO, this wasn't important enough to block the PR over. _Also I'm impatient and wanted that setting_.
After I merged the PR I created the issues and added the numbers myself.

## Validation Steps Performed
This PR makes use of the UiaRenderer by attaching it to the TerminalControl and setting up selectionChanged events for accessibility.
Part 1: attaching the UiaRenderer
The uiaRenderer is treated very similarly to the dxRenderer. We have a unique_ptr ref to it in the TermControl. This gets populated when the TermControlAutomationPeer is created (thus enabling accessibility).
To prevent every TermControl from sending signals simultaneously, we specifically only enable whichever one is in an active pane.
The UiaRenderer needs to send encoded events to the automation provider (in this case, TermControlAutomationPeer). We needed our own automation events so that we can reuse this model for ConHost. This is the purpose of IUiaEventDispatcher.
We need a dispatcher for the UiaRenderer. Otherwise, we would do a lot of work to find out when to fire an event, but we wouldn't have a way of doing that.
Part 2: hooking up selection events
This provides a little bit of polish to hooking it up before. Primarily to actually make it work. This includes returning S_FALSE instead of E_NOTIMPL.
The main thing here really is just how to detect if a selection has changed. This also shows how clean adding more events will be in the future!
This pull request implements the new
`ITerminalConnection::ConnectionState` interface (enum, event) and
connects it through TerminalControl to Pane, Tab and App as specified in
#2039. It does so to implement `closeOnExit` = `graceful` in addition to
the other two normal CoE types.
It also:
* exposes the singleton `CascadiaSettings` through a function that
looks it up by using the current Xaml application's `AppLogic`.
* In so doing, we've broken up the weird runaround where App tells
TerminalSettings to CloseOnExit and then later another part of App
_asks TerminalControl_ to tell it what TerminalSettings said App
told it earlier. `:crazy_eyes:`
* wires up a bunch of connection state points to `AzureConnection`.
This required moving the Azure connection's state machine to use another
enum name (oops).
* ships a helper class for managing connection state transitions.
* contains a bunch of template magic.
* introduces `WINRT_CALLBACK`, a oneshot callback like `TYPED_EVENT`.
* replaces a bunch of disparate `_connecting` and `_closing` members
with just one uberstate.
* updates the JSON schema and defaults to prefer closeOnExit: graceful
* updates all relevant documentation

## Summary of the Pull Request
This PR implements resetFontSize keybindings, with default keybindings `ctrl+0`.
## PR Checklist
* [x] Closes#3319
* [x] CLA signed. If not, go over [here](https://cla.opensource.microsoft.com/microsoft/Terminal) and sign the CLA
* [ ] Tests added/passed
* [ ] Requires documentation to be updated
## Validation Steps Performed
Tested manually.
-----------------------------------------
* Add resetFontSize keybindings (#3319)
* update doc files
* Refactor AdjustFontSize & ResetFontSize to use _SetFontSize (#3319)
* Ran clang-format on TermControl
* Fix function usage change
TerminalControl doesn't use any of the built in text input and edit
controls provided by XAML for text input, which means TermianlControl
needs to communicate with the Text Services Framework (TSF) in order to
provide Input Method Editor (IME) support. Just like the rest of
Terminal we get to take advantage of newer APIs (Windows.UI.Text.Core)
namespace to provide support vs. the old TSF 1.0.
Windows.UI.Text.Core handles communication between a text edit control
and the text services primarily through a CoreTextEditContext object.
This change introduces a new UserControl TSFInputControl which is a
custom EditControl similar to the CustomEditControl sample[1].
TSFInputControl is similar (overlay with IME text) to how old console
(conimeinfo) handled IME.
# Details
TSFInputControl is a Windows.UI.Xaml.Controls.UserControl
TSFInputControl contains a Canvas control for absolution positioning a
TextBlock control within its containing control (TerminalControl).
The TextBlock control is used for displaying candidate text from the
IME. When the user makes a choice in the IME the TextBlock is cleared
and the text is written to the Terminal buffer like normal text.
TSFInputControl creates an instance of the CoreTextEditContext and
attaches appropriate event handlers to CoreTextEditContext in order to
interact with the IME.
A good write-up on how to interact with CoreTextEditContext can be found
here[2].
## Text Updates
Text updates from the IME come in on the TextUpdating event handler,
text updates are stored in an internal buffer (_inputBuffer).
## Completed Text
Once a user selects a text in the IME, the CompositionCompleted handler
is invoked. The input buffer (_inputBuffer) is written to the Terminal
buffer, _inputBuffer is cleared and Canvas and TextBlock controls are
hidden until the user starts a composition session again.
## Positioning
Telling the IME where to properly position itself was the hardest part
of this change. The IME expects to know it's location in screen
coordinates as supposed to client coordinates. This is pretty easy if
you are a pure UWP, but since we are hosted inside a XAMLIsland the
client to screen coordinate translation is a little harder.
### Calculating Screen Coordinates
1. Obtaining the Window position in Screen coordinates.
2. Determining the Client coordinate of the cursor.
3. Converting the Client coordinate of the cursor to Screen coordinates.
4. Offsetting the X and Y coordinate of the cursor by the position of
the TerminalControl within the window (tabs if present, margins, etc..).
5. Applying any scale factor of the display.
Once we have the right position in screen coordinates, this is supplied
in the LayoutBounds of the CoreTextLayoutRequestedEventArgs which lets
the IME know where to position itself on the Screen.
## Font Information/Cursor/Writing to Terminal
3 events were added to the TSFInputControl to create a loosely-coupled
implementation between the TerminalControl and the TSFInputControl.
These events are used for obtaining Font information from the
TerminalControl, getting the Cursor position and writing to the terminal
buffer.
## Known Issues
- Width of TextBlock is hardcoded to 200 pixels and most likely should
adjust to the available width of the current input line on the console
(#3640)
- Entering text in the middle of an existing set of text has TextBlock
render under existing text. Current Console behavior here isn't good
experience either (writes over text)
- Text input at edges of window is clipped versus wrapping around to
next line. This isn't any worse than the original command line, but
Terminal should be better (#3657)
## Future Considerations
Ideally, we'd be able to interact with the console buffer directly and
replace characters as the user types.
## Validation
General steps to try functionality
- Open Console
- Switch to Simplified Chinese (Shortcut: Windows+Spacebar)
- Switch to Chinese mode on language bar
Scenarios validated:
- As user types unformatted candidates appear on command line and IME
renders in correct position under unformatted characters.
- User can dismiss IME and text doesn't appear on command line
- Switch back to English mode, functions like normal
- New tab has proper behavior
- Switching between tabs has proper behavior
- Switching away from Terminal Window with IME present causes IME to
disappear

<!-- Provide a more detailed description of the PR, other things fixed or any additional comments/features here -->
## Detailed Description of the Pull Request / Additional comments
Mostly similar to PR #1224. Added a new static method `GenRTF` in `TextBuffer` that is responsible
for generating the RTF representation of a given text. The generated RTF is added to the `DataPackage` that is ultimately passed to the clipboard.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Validated by copy pasting text from the terminal to WordPad. Validated with different colors to make sure that is working. (MS Word seems to prefer HTML data from the clipboard instead of RTF.)
<hr>
* Copy RTF data to the clipboard
* Added comment explaining various parts of the header
* Fixed static code analysis issues and added noexcept to GenRTF()
* Removed noexcept

## Summary of the Pull Request
This introduces a setting to both Profiles and ColorSchemes called <code>selectionBackground</code> that allows you to change the selection background color to what's specified. If <code>selectionBackground</code> isn't set in either the profile or color scheme, it'll default to what it was before - white.

## Validation Steps Performed
- Added selectionBackground to existing profile and colorscheme tests.
- Verified that the color does change to what I expect it to be when I add "selectionBackground" to either/both a profile and a color scheme.
<hr>
* adding selectionBackground to ColorScheme and TerminalSettings
* Changing PaintSelection inside the renderers to take a SelectionBackground COLORREF
* changes to conhost and terminal renderdata, and to terminal settings and core
* IT WORKS
* modification of unit tests, json schemas, reordering of functions
* more movement
* changed a couple of unit tests to add selectionBackground, added the setting to schemas, also added the optional setting to profiles
* default selection background should be slightly offwhite like the default foreground is
* reverting changes to .sln
* cleaning up
* adding comment
* oops
* added clangformat to my vs hehe
* moving selectionBackground to IControlSettings and removing from ICoreSettings
* trying to figure out why the WHOLE FILE LOOKS LIKE ITS CHANGED
* here it goes again
* pls
* adding default foreground as the default for selection background in dx

## Detailed Description of the Pull Request / Additional comments
Combination of the PRs #1094, #2390, and #3314, especially as discussed in #3314.
In short, this changes line endings from Windows-space \r\n to the more universal \r.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Copied and pasted text into the terminal without the patch, line endings were doubled.
With the patch, line endings weren't doubled.
--------------------
* Replacing \r\n line endings with \r line endings
* Fixing Formatting
This commit cleans up and deduplicates all of the common build
preamble/postamble across exe, dll, lib and c++/winrt projects.
The following specific changes have been made:
* All projects now define their ConfigurationType
* All projects now set all their properties *before* including a common
build file (or any other build files)
* cppwinrt.pre and cppwinrt.post now delegate most of their
configuration to common.pre and common.post
* (becuase of the above,) all build options are conserved between
console and c++/winrt components, including specific warnings and
preprocessor definitions.
* More properties that are configurable per-project are now
conditioned so the common props don't override them.
* The exe, dll, exe.or.dll, and lib postincludes have been merged into
pre or post and switched based on condition as required
* Shared items (-shared, -common) are now explicitly vcxitems instead of
vcxproj files.
* The link line is now manipulated after Microsoft.Cpp sets it, so the
libraries we specify "win". All console things link first against
onecore_apiset.lib.
* Fix all compilation errors caused by build unification
* Move CascadiaPackage's resources into a separate item file
Fixes#922.
* Switch all of the UIA providers to WRL::RuntimeClass
Fixes#3209.

From Egmont Koblinger:
> In terminal emulation, apps have to be able to print something and
keep track of the cursor, whereas they by design have no idea of the
font being used. In many terminals the font can also be changed runtime
and it's absolutely not feasible to then rearrange the cells. In some
other cases there is no font at all (e.g. the libvterm headless terminal
emulation library, or a detached screen/tmux), or there are multiple
fonts at once (a screen/tmux attached from multiple graphical
emulators).
> The only way to do that is via some external agreement on the number
of cells, which is typically the Unicode EastAsianWidth, often accessed
via wcwidth(). It's not perfect (changes through Unicode versions, has
ambiguous characters, etc.) but is still the best we have.
> glibc's wcwidth() reports 1 for ambiguous width characters, so the de
facto standard is that in terminals they are narrow.
> If the glyph is wider then the terminal has to figure out what to do.
It could crop it (newer versions of Konsole, as far as I know), overflow
to the right (VTE), shrink it (Kitty I believe does this), etc.

Salient point from proposed update to Unicode Standard Annex 11:
> Note: The East_Asian_Width property is not intended for use by modern
terminal emulators without appropriate tailoring on a case-by-case
basis.

* We had to move to the final API:
* Items -> TabItems
* Items.VectorChanged -> TabItemsChanged
* TabClose -> TabCloseRequested
* TabViewItem.Icon -> TabViewItem.IconSource
* TabRowControl has been converted to a ContentPresenter, which
simplifies its logic a little bit.
* TerminalPage now differentiates MUX and WUX a little better
* Because of the change from Icon to IconSource in TabViewItem,
Utils::GetColoredIcon needed to be augmented to support MUX IconSources.
It was still necessary to use for WUX, so it's been templatized.
* I moved us from WUX SplitButton to MUX SplitButton and brought the
style in line with the one typically provided by TabView.
* Some of our local controls have had their backgrounds removed so
they're more amenable to being placed on other surfaces.
* I'm suppressing the TabView's padding.
* I removed a number of apparently dead methods from App.
* I've simplified the dragbar's sizing logic and eventing.
* The winmd harvester needed to be taught to not try to copy winmds for
framework packages.
* We now only initialize the terminal once we know the size

This adds the WPF control to our project, courtesy of the Visual Studio team.
It re-hosts the Terminal Control components inside a reusable WPF adapter so it can be composed onto C# type surfaces like Visual Studio requires.
It turns out that if you CATCH_LOG without including this file, and you
end up catching a C++/WinRT hresult_exception, IT TURNS IT INTO A
FAILFAST.

* Revert "Add source linking information during the build (#2857)"
This reverts commit 6b728cd6d0.
* Need reference to renderer base inside UnitTests_TerminalCore
* add dependency for TerminalControl to Types project.
* Set build to single threaded as parallel build is broken by 16.3 build toolchain.
* Disable new rule C26814 as it's breaking builds
Wrote a follow up task #2941 to roll it out later.
* Add noexcept to dx header.
Copies source linking scripts and processes from Microsoft/Microsoft-UI-XAML. This embeds source information inside the PDBs in two formats: One for WinDBG using a PowerShell script that runs during the build, and one for Visual Studio using the Microsoft.SourceLink.GitHub NuGet pacakge. Sources are automatically pulled from raw.githubusercontent.com when debugging a release build inside either of these utilities as of this change.
* Remove WindowUiaProvider entry points
Make TerminalAutomationPeer not crash the app if creation failed.
* code format
