Fix NativeAnimatedNodesManager registering event listener multiple times

Browse Source 
Summary:
Noticed that (LockFree)EventDispatcherImpl had NativeAnimatedNodesManager as a listener 100+ times, as listener registration can happen multiple times from Animated node creation. Since listener management on event dispatcher is thread-safe, we can avoid the thread hop for this.
