rn-android | Allow injecting a custom ChoreographerProvider via ReactNativeHost into construction of ReactInstanceManager.

Summary:
Further propagating extension to the Android choreographer, now allowing to override it from the perspective of ReactNativeHost/ReactInstanceManager(Builder).

Changelog:
[Android][Added] ReactChoreographer can now use an implementation substitution instead of relying on android.view.Choreographer directly.
