Implement native Animated value listeners on Android

Browse Source 
Summary:
Adds support for `Animated.Value#addListener` for native driven nodes on Android. This is based on work by skevy in the exponent RN fork. Also adds a UIExplorer example.

** Test plan **
Run unit tests

Tested that by adding a listener to a native driven animated node and checked that the listener callback is called properly.

Also tested that it doesn't crash on iOS that doesn't support this yet.
Closes https://github.com/facebook/react-native/pull/8844
