Fix the case sensitivity button in search on High Contrast (#5088)
Because the `Path` inside the case sensitivity button is not _text_,
it wasn't getting themed by the Xaml runtime's text style.

deps: upgrade CppWinRT to 2.0.200316.3, gsl to v2.1.0 (#4536)
This commit upgrades C++/WinRT to 2.0.200316.3 and fixes a couple of the
transitive dependency issues we had in the process.

Because the latest version has better dependency resolution, we're able
to properly depend on Microsoft.UI.Xaml and the Toolkit in TerminalApp
and TerminalAppLib so we no longer need to manually include .dll and
.pri files.

Because of nebulous _other_ changes in dependency resolution,
WindowsTerminalUniversal isn't picking up transitive .winmd dependencies
from TerminalApp, and needs to include them as ProjectReferences
directly. This was already happening transitively, so now it's explicit.

I've also taken the time to upgrade GSL to v2.1.0, the last release
before they removed span::at and blew up our world.

Set the ComponentResourceLocation for our DLL projects (#5031)
These projects load Xaml components that have Uids, but those Uids just
weren't working because Xaml components are, by default, loaded in
"Application" scope. Application scope is great if the resource producer
is the EXE project.

Application scope means that resources are looked up at the resource
root, but DLLs with resources don't produce resources at the root. They
produce resources at a root named after the DLL.

Setting the Xaml component resource location to Nested makes sure the
Xaml resource loader loads resources from the right places.

Allow IME Text Wrapping (#5005)
## Summary of the Pull Request
This PR turns on TextWrapping on `TSFInputControl::TextBlock`. Once the TextBlock hits the end of the Terminal window, it will wrap downwards, but the TextBlock will have as much width as it had when composition started. Unfortunately, this means if composition starts right at the end of the Terminal with enough width for just one character, there will be a vertical line of characters down the right side of the Terminal 😅. It's definitely not ideal, and I imagine this won't be the last time we visit this issue, but for now users can see what they're typing.

Fire UIA Events for Output and Cursor Movement (#4826)
## Summary of the Pull Request
This notifies automation clients (i.e.: NVDA, narrator, etc...) of new output being rendered to the screen.

## References
Close #2447 - Signaling for new output and cursor
Close #3791 - fixed by signaling cursor changes

## Detailed Description of the Pull Request / Additional comments
- Added tracing for UiaRenderer. This makes it easier to debug issues with notifying an automation client.
- Fire TextChanged automation events when new content is output to the screen.

## Validation Steps Performed
Verified with NVDA [1]

## Narrator
Narrator works _better_, but is unable to detect new output consistently. There is no harm for narrator when this change goes in.

Ignore KeyDown events during Alt-Numpad Input (#4965)
## Summary of the Pull Request
Alt-Numpad# input would be escaping each numkey before sending it through. This would result in some weird behavior, for example, in powershell, where the first alt-numpad# would start digit argument and once the user releases alt, a character is sent through and digit argument would repeat that character X times. To resolve this, we simply need to ignore KeyDowns where Alt is held and a Numpad# is pressed. 

Once Alt is released, we'll receive a character through `TSFInputControl`, not `TermControl::CharacterHandler`. It seems that the `CoreTextEditContext` in `TSFInputControl` intercepts the character before it gets to `TermControl`. TSF will then send the received character through as normal.

Add support for setting the cursor visibility in Terminal (#4902)
Adds support for setting the cursor visibility in Terminal. Visibility
is a property entirely independent from whether the cursor is "on" or
not. The cursor blinker _should_ change the "IsOn" property. It was
actually changing the "Visible" property, which was incorrect. This PR
additionally corrects the naming of the method used by the cursor
blinker, and makes it do the right thing.

I added a pair of tests, one taken straight from conhost. In
copy-pasting that test, I took it a step further and implemented
`^[[?12h`, `^[[?12l`, which enables/disables cursor blinking, for the
`TerminalCore`. THIS DOES NOT ADD SUPPORT FOR DISABLING BLINKING IN THE
APP. Conpty doesn't emit the blinking on/off sequences quite yet, but
when it _does_, the Terminal will be ready.

Synthesize VT mouse events and add mouse support to Terminal (#4859)
## Summary of the Pull Request
Make TerminalControl synthesize mouse events and Terminal send them to
the TerminalInput's MouseInput module.

The implementation here takes significant inspiration from how we handle
KeyEvents.

## References
Closes #545 - VT Mouse Mode (Terminal)
References #376 - VT Mouse Mode (ConPty)

### TerminalControl
- `_TrySendMouseEvent` attempts to send a mouse event via TermInput.
  Similar to `_TrySendKeyEvent`
- Use the above function to try and send the mouse event _before_
  deciding to modify the selection

### TerminalApi
- Hookup (re)setting the various modes to handle VT Input
- Terminal is _always_ in VT Input mode (important for #4856)

### TerminalDispatch

### TerminalInput
- Convert the mouse input position from viewport position to buffer
  position
- Then send it over to the MouseInput in TerminalInput to actually do it

Show InputPanel on focus and pointer press (#4867)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
I originally thought that setting `TSFInputControl::_editContext.InputPaneDisplayPolicy` to be Automatic would allow the InputPanel to show and hide automatically when `TSFInputControl` gains and loses focus. It doesn't seem to behave that way, so we'll show the InputPanel manually. 

I'll show the panel during `PointerPressedHandler` and during `GotFocusHandler`. A user will have the on-screen keyboard pop up when getting focus, but if they close the keyboard, they can simply re-tap on the terminal to bring it back up.

## Summary of the Pull Request

Send TSF input buffer starting from _activeTextStart to the end of the buffer (#4836)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Emoji composition was only being shown one letter at a time. This is because of the way I expected `CoreTextTextUpdatingEventArgs.Range` to be provided to TSFInputControl during composition (for Chinese/Japanese IME). Emoji IME composition gives the `StartCaretPosition` as the same as `EndCaretPosition`, unlike how for Chinese/Japanese IME, `StartCaretPosition` is usually the start of the composition and `EndCaretPosition` is the latest character in the composition. The solution is to change the `_inputBuffer.substr()` call to simply grab all of the buffer starting from `_activeTextStart`. This way I can ensure that I grab all of the "active text", instead of trusting the given `args.Range` to tell me the active text.

Abstract GetTextForClipboard() for UIA (#4578)
## Summary of the Pull Request
`GetTextForClipboard` already exists in the TextBuffer. It makes sense to use that for UIA as well. This changes the behavior or `GetText()` such that it does not remove leading/trailing whitespace anymore. That is more of an expected behavior.

## References
This also contributes to...
- #4509: UIA Box Selection
- #2447: UIA Signaling for Selection
- #1354: UIA support for Wide Glyphs
Now that the expansion occurs at before render-time, the selection anchors are an accurate representation of what is selected. We just need to move GetText to the TextBuffer. Then we can have those three issues just rely on code from the text buffer. This also means ConHost gets some of this stuff for free 😀

## Detailed Description of the Pull Request / Additional comments
- `TextBuffer::GetTextForClipboard()` --> `GetText()`
- `TextBuffer::GetText()` no longer requires GetForegroundColor/GetBackgroundColor. If either of these are not defined, we return a `TextAndColor` with only the `text` field populated.
- renamed a few parameters for copying text to the clipboard for clarity
- Updated `UiaTextRange::GetText()` to use `TextBuffer::GetText()`

## Validation Steps Performed

Polish AutomationProperties and UIA Tree Navigation (#4805)
AutomationProperties of interest in this PR include...
- Name: the name of a UI element (generally used as the main identifier
  for it)
- HelpText: an additional description for a more complex UI element
- AccessibilityView[1]
  - Raw: hide from the UIA tree. Only navigate to this if you know what
    you're doing
  - Control: a control without any content in it. Basically, a point at
    which the user can make a decision as to how to navigate the tree or
    invoke an action.
  - Content: a control that also has content to present to the user.

I set a few more AutomationProperties throughout Windows Terminal...
- MinMaxClose Control: hidden (we can/should rely on the true buttons
  that we are hiding)
- SplitButton: Name and Help text (currently ignored due to #4804, but
  having it in the resource file won't cause any problems)
- SearchBox: added a more specific name to the close button
- BackgroundImage: hide it

Tunnel F7 keypresses directly into special handlers in TermControl (#4807)
The Xaml input stack doesn't allow an application to suppress the "caret
browsing" dialog experience triggered when you press F7.

The official recommendation from the Xaml team is to catch F7 before we
hand it off.

This commit introduces a special F7 handler and an ad-hoc implementation of event bubbling.
Runtime classes implementing a custom IF7Listener interface are
considered during a modified focus parent walk to determine who can
handle F7 specifically.

If the recipient control handles F7, we suppress the message completely.

This event bubbler has some minor issues -- the search box will not be
able to receive F7 because its parent control implements the handler.
Since search is already mostly a text box, it doesn't _need_ special
caret browsing functionality as far as I can tell.

TermControl implements its OnF7Pressed handler by synthesizing a
keybindings event and an event to feed into Terminal Core directly.

It's not possible to create a synthetic KeyPressRoutedEvent; if it were,
I would have just popped one into the traditional input queue. :)

Fixes #638.

Make Korean IME input more consistent (#4796)
## Summary of the Pull Request
Korean IME was not working correctly due to way we were clearing the input buffer inside of `TSFInputControl`. We wanted to clear our input buffer and tell TSF to clear its input buffer as well when we receive a `CompositionCompleted` event. This works fine in some IME languages such as Chinese and Japanese. However, Korean IME composes characters differently in such a way where we can't tell TSF to clear their buffer during a `CompositionCompleted` event because it would clear the character that triggered the `CompositionCompleted` event in the first place.

The solution in this PR is to keep our `_inputBuffer` intact until the user presses <kbd>Enter</kbd> or <kbd>Esc</kbd>, in which case we clear our buffer and the TSF buffer. I've chosen these two keys because it seems to make sense to clear the buffer after text is sent to the terminal with <kbd>Enter</kbd>, and <kbd>Esc</kbd> usually means to cancel a current composition anyway.

This means we need to keep track of our last known "Composition Start Point", which is represented by `_activeTextStart`. Whenever we complete a composition, we'll send the portion of the input buffer between `_activeTextStart` and the end of the input buffer to the terminal. Then, we'll update `_activeTextStart` to be the end of the input buffer so that the next time we send text to the terminal, we'll only send the portion of our buffer that's "active".

Allow IME input in Search Box (#4723)
## Summary of the Pull Request
Currently, when the user attempts to type using IME while the Search Box is focused, the input goes to the terminal instead. This is due to the fact that the `TSFInputControl` assumes it's in control whenever TermControl gets focus. So, it'll intercept IME input before the Search Box receives it. We simply need to modify `TermControl::GotFocus` to check if the SearchBox has focus. If it does, `TSFInputControl::NotifyFocusEnter` shouldn't be called.

As a small side fix, I've also disabled the terminal cursor blinking when the Search Box has focus.

Thinking a little further, if we have more features in the future that behave like search box (i.e. advanced tab switcher, or any other XAML controls that pop up) and require text input, we might need to create a sort of "AnyOtherTextControlInFocus" function to see if TSFInputControl should receive focus or not.

Display Emojis, Kaomojis, and symbols while in IME mode (#4688)
## Summary of the Pull Request
Currently, while in IME mode, selections with the Emoji/Kaomoji/Symbol Picker (which is brought up with <kbd>win+.</kbd>) are not displayed until the user starts a new composition. This is due to the fact that we hide the TextBlock when we receive a CompositionCompleted event, and we only show the TextBlock when we receive a CompositionStarted event. Input from the picker does not count as a composition, so we were never showing the text box, even if the symbols were thrown into the inputBuffer. In addition, we weren't receiving CompositionStarted events when we expected to.

We should be showing the TextBlock when we receive _any_ text, so we should make the TextBlock visible inside of `TextUpdatingHandler`. Furthermore, some really helpful discussion in #3745 around wrapping the `NotifyTextChanged` call with a `NotifyFocusLeave` and a `NotifyFocusEnter` allowed the control to much more consistently determine when a CompositionStarted and a CompositionEnded.

I've also went around and replaced casts with saturating casts, and have removed the line that sets the `textBlock.Width()` so that it would automatically set its width. This resolves the issue where while composing a sentence, the textBlock would be too small to contain all the text, so it would be cut off, but the composition is still valid and still able to continue.

hook up UIA tree to WPF control (#4548)
This PR hooks up the existing UIA implementation to the WPF control. Some existing code that was specific to the UWP terminal control could be shared so that has been refactored to a common location as well.

## Validation Steps Performed
WPF control was brought up in UISpy and the UIA tree was verified. NVDA was then used to check that screen readers were operating properly.

Make ScreenInfoUiaProvider::GetSelection() Return One Selection (#4466)
## Summary of the Pull Request
We used to return multiple text ranges to represent one selection. We only support one selection at a time, so we should only return one range.

Additionally, I moved all TriggerSelection() calls to the renderer from Terminal to TermControl for consistency. This ensures we only call it _once_ when we make a change to our selection state.

Fix duplicate copyOnSelect when clicking on an unfocused terminal (#4596)
## Summary of the Pull Request
Currently, clicking on an unfocused terminal with a selection active will trigger `copyOnSelect`. This is because the check for `copyOnSelect` and copying to the clipboard is bound to when the Pointer is released. This works fine for when a user performs a click-drag selection, but it inadvertently also triggers when the user performs a single click on an unfocused terminal. We expect `copyOnSelect` to trigger only on the first time a selection is completed. 

This PR will allow the user to single click on an unfocused terminal that has a selection active without triggering a copyOnSelect. It also ensures that any click-drag selection, whether it's on an unfocused or focused terminal, will trigger copyOnSelect.

## PR Checklist
* [x] Closes #4255

## Validation Steps Performed
Performed manual testing involving permutations of multiple panes, tabs, in focus, and out of focus.

James 8392d6b647 Fix touchpad and touchscreen scrolling (#4554)
Fixed inconsistent scrolling when using both touchscreen and precision
touchpad.

Scrolling jumpiness is caused by rounding errors. Instead of retrieving
the current scrolling value from `GetScrollOffset`, which is already
rounded in `int`, let the scrolling operation to operate on
`_scrollBar`'s `Value` directly (which uses `double`) in
`TermControl.cpp`.

TermControl now also respects WHEEL_DELTA, which it was previously
ignoring, to determine how many scroll wheel detents were used.

Testing scrolling on the following scenario manually:

- nonscrollable terminal (e.g. the window is large enough to contain the
  current buffer).
- scrolling to the topmost and bottom-most.
- scrolling TUI apps such as `nano` and `more` in WSL.
- after clearing the terminal, both in cmd and WSL.

... has the same behavior between using touchscreen or precision trackpad
and regular mouse wheel.

Fix click-drag selection on an unfocused Terminal (#4506)
## Summary of the Pull Request
This PR tries to address some of the weird interactions with pointer pressed events when the Terminal isn't in focus. Here's the four things that have changed as part of this PR;

1. This PR will allow the user to be able to make a selection with a click-drag without having to first perform a single click on a tab/pane to bring it to focus. 
2. Another weird bug that's fixed in this PR is where trying to make a selection on an unfocused tab when it already has a selection active will simply extend the existing selection instead of making a new one.
3. Not related to the issue that his PR closes: a right click will now focus the tab/pane.

I've made sure that we still have the existing functionality where a single click on an unfocused tab/pane does not make a single-cell selection and just focuses the tab/pane.

- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomKeybindings" event
- "Keybindings" value is the entire JSON segment that describes the user keybindings from `settings.json`.
5. Do people change their default profile from the PowerShell one we set? If so, to what? (Should we not set PowerShell as the default? Should we adjust the ranking of our dynamic generators to favor the most popular ones to bubble to the top?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}

uia: add support for scrolling the viewport (#4525)
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_!

## 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.

Introduce UiaTextRangeBase::FindText() for Accessibility (#4373)
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.

Refactor UiaTextRange For Improved Navigation and Reliability (#4018)
## 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.

## References
#3976 - I believe this might have been a result of improperly handling degenerate ranges. Fixed here.
#3895 - reduced the duplicate code. No need to separate into different files
#2160 - same as #3976 above
#1993 - I think just about everything is no longer static

## PR Checklist
* [x] Closes #3895, Closes #1993, Closes #3976, Closes #2160 
* [x] CLA signed
* [x] Tests added/passed

## 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.

🛑 **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

*With the exception of three functions whose signatures cannot be changed due to inheritance and function overriding in `TermControlAutomationPeer` [`L44`](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalControl/TermControlAutomationPeer.cpp#L44), [`L58`](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalControl/TermControlAutomationPeer.cpp#L58),  [`L72`](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalControl/TermControlAutomationPeer.cpp#L72).

## 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.
