Subject: [PATCH] Fix natively driven animated.event for bubbling PointerEvents

Summary:
Changelog: [Internal]

Override logic for determining whether a dispatched `Event` triggers a native `EventAnimationDriver`.

Natively driven AnimatedEvents on bubbling events is not supported.  `PointerEvents` requires this and this diff adds custom matching logic such that if a parent specifies an `AnimatedEvent` on `onPointerMove` and a child view dispatches it, the `AnimatedEvent` will still fire.
