Goal: Remove `CursorBlinker`.
Problem: Spooky action at a distance via `Cursor::HasMoved`.
Solution: Moved all the a11y event raising into `_stream.cpp` and pray
for the best.
Goal: Prevent node.js from tanking conhost performance via MSAA (WHY).
Problem: `ServiceLocator`.
Solution: Unserviced the locator. Debounced event raising. Performance
increased by >10x.
Problem 2: Lots of files changed.
This PR is a prerequisite for #19330
## Validation Steps Performed
Ran NVDA with and without UIA enabled and with different delays. ✅
`InteractivityOneCore` and `RendererWddmCon` were the last two remaining
projects which are relevant for our internal console builds, but couldn't be
easily compiled publicly by users on GitHub. This commit adds all definitions
required to compile the two projects into dysfunctional libraries at least.
(Since the added definitions are deliberately incorrect.)
Additionally this commit fixes the AuditMode build for the two projects.
## Validation Steps Performed
The two new projects compile fine.
