basic useNativeDriver functionality

Summary:
Not super clean, but not terrible.

Unfortunately this still relies on the old Paper UIManager calling delegate methods to flush the operations queues. This will work for Marketplace You since Paper will be active, but we need to fix this, along with Animated Events which don't work at all yet.

Random aside: it seems like taps are less responsive in fabric vs. paper, at least on iOS. There is a sporadic delay between the touches event coming in nativly to the JS callback invoking the native module function to start the animation - this will need some debugging.
