    This PR adds 2 features to RenderAndroidView and AndroidView:
    
    1. Hit testing behavior
    Adds a `PlatformViewHitTestBehavior` which is similar to
    `HitTestBehavior` without the `deferToChild` option (as platform views
    don't have child render objects) and with a `transparent` option which
    prevents it from forwarding any events to the Android view.
    
    2. MotionEvent recomposing logic
    FlutterView and the framework `converter.dart` are working together to
    transform each Android MotionEvent object into one or more
    `PointerEvent` objects.
    
    This PR adds the reverse logic (in _MotionEventDispatcher which is used
    by RenderAndroidView) which turns a stream of PointerEvent objects into
    MotionEvent objects.
    
    The correctness of the recomposing logic is tested in an integration
    test which will land in a separate PR (the unit test PR is pretty big,
    trying to keep as many bite-size PRs for reviewer's convenience)
