## Summary of the Pull Request This forces the `TermControl` to only use `ControlCore` and `ControlInteractivity` via their WinRT projections. We want this, because WinRT projections can be used across process boundaries. In the future, `ControlCore` and `ControlInteractivity` are going to be living in a different process entirely from `TermControl`. By enforcing this boundary now, we can make sure that they will work seamlessly in the future. ## References * Tear-out: #1256 * Megathread: #5000 * Project: https://github.com/microsoft/terminal/projects/5 ## PR Checklist * [x] Closes https://github.com/microsoft/terminal/projects/5#card-50760270 * [x] I work here * [x] Tests added/passed * [n/a] Requires documentation to be updated ## Detailed Description of the Pull Request / Additional comments Most all this was just converting pure c++ types to winrt types when possible. I've added a couple helper projections with `til` converters, which made most of this really easy. The "`MouseButtonState` needs to be composed of `Int32`s instead of `bool`s" is MENTAL. I have no idea why this is, but when I had the control OOP in the sample, that would crash when trying to de-marshal the bools. BODGY. The biggest changes are in the way the UIA stuff is hooked up. The UiaEngine needs to be attached directly to the `Renderer`, and it can't be easily projected, so it needs to live next to the `ControlCore`. But the `TermControlAutomationPeer` needed the `UiaEngine` to help implement some interfaces. Now, there's a new layer we've introduced. `InteractivityAutomationPeer` does the `ITextProvider`, `IControlAccessibilityInfo` and the `IUiaEventDispatcher` thing. `TermControlAutomationPeer` now has a `InteractivityAutomationPeer` stashed inside itself, so that it can ask the interactivity layer to do the real work. We still need the `TermControlAutomationPeer` though, to be able to attach to the real UI tree. ## Validation Steps Performed The terminal behaves basically the same as before. Most importantly, I whipped out Accessibility Insights, and the Terminal looks the same as before.
