Create more general extension mechanism for NativeViewGestureHandler on Android

[j-piasecki]

Description

This PR:

• changes StateChangeHook to NativeViewGestureHandlerHook and adds more methods to it
• adds default hook that doesn't change the behavior of the gesture
• adds onPrepare method to base GestureHandler allowing handlers to perform specific actions
• adds logic for using correct hook in onPrepare method
• adds super call to shouldRecognizeSimultaneously in NativeViewGestureHandler - without this simultaneousHandlers prop is effectively ignored

Test plan

Tested on the Example app.
