Mouad Debbar ee266e5318 [web] PointerBinding per view (flutter/engine#48248) ...

- Move initialization of `PointerBinding`/`KeyboardBinding` out of `FlutterViewEmbedder`.
- `computeEventOffsetToTarget` properly handles events within a given view.
- `PointerBinding` operates on the given Flutter view (it still listens to some `domWindow` events for the implicit view).
    - Stop using globals e.g. `ui.window`, `KeyboardBinding.instance`, `SafariPointerEventWorkaround.instance`, etc.
- `pointer_binding_test.dart` doesn't use globals either.
- `clickDebouncer` is now a static property on `PointerBinding`.
