Summary: While refactoring `Animated`, I noticed that many subclasses of `AnimatedNode` override `__attach` without invoking the superclass method, even though we do this for `__detach`. In order to minimize surprise (e.g. if someone were to add logic into `AnimatedNode.prototype.__attach`), this diff updates all method overrides to invoke `super.__attach()`.

Summary: Pull Request resolved: facebook#48511 {D60499583} added a new`onUserDrivenAnimationEnded` listener that requires `AnimatedValue` instances to have up-to-date values reported by `onAnimatedValueUpdate` (if native driver is in use). Previously, the only way to ensure `onAnimatedValueUpdate` events were always fired to update JavaScript values in `AnimatedValue` instance was to attach a listener — even an empty one. This is exactly what D60499583 did: it traverses `props` for `AnimatedNode` instances and attaches listeners to them. However, this is really inefficient and makes the code extra convoluted. Instead, this diff changes `AnimatedValue` so that it always subscribes to changes in `__attach`, and then it cleans up the extraneous props traversal and "empty listener" logic.

Summary: Currently, `AnimatedNode` implements logic to start listening to updates on the current native node if a listener is added. However, the `startListeningToAnimatedNodeValue` native module method only supports native tags for instances of `AnimatedValue`, which is a subclass of `AnimatedNode`. In fact… * On Android, [`startListeningToAnimatedNodeValue`](https://fburl.com/code/bdsl4sro) throws if the node is not an instance of `ValueAnimatedNode`. * On iOS, [`startListeningToAnimatedNodeValue`](https://fburl.com/code/hlpk1rzk) does nothing if node is not an instance of `RCTValueAnimatedNode`. As such, this refactors `AnimatedNode` to never manage this subscription for native nodes. Instead, the logic is moved into the `AnimatedValue` subclass, ensuring that we never accidentally try to `startListeningToAnimatedNodeValue` with non-`AnimatedValue` native tags.
