Connect YUI to Windows host input, accessibility, and editing services.

```yh
external thing yuiWindowsHostInputAdapter
```

- windowHandle handle: Stores handle as windowHandle.
- int lastSequence: Stores last sequence as int.
- int lastPointerDownSequence: Stores last pointer down sequence as int.
- bool primaryPressed: Stores primary pressed as bool.
- int pressedPointerId: Stores pressed pointer id as int.
- yuiWindowsHostInputAdapter(windowHandle handle): Yui windows host input adapter.
- PointerFromLatest(int sequence, text kind) returns nativePointerRecord: Pointer from latest.
- PointerFromDurableDown(int sequence) returns nativePointerRecord: Pointer from durable down.
- Poll() returns yuiWindowsHostInputEvent: Poll.
