----------
[Changed][General] Move callback-related logic to `AnimatedNode` class in order to make it possible to add the listener for other animated nodes than `AnimatedValue`.
I observed that native code appears to be fully prepared for listening not only to animated value but animated nodes generally. Therefore I managed to modify js code for exposing `addListener` method from `AnimatedNode` class instead of `AnimatedValue`. It called for some minor changes, which are not breaking.
If you're fine with these changes, I could add proper docs if needed.
