remove enable_shared_from_this from NativeAnimatedNodesManager (#51589)

Summary:
Pull Request resolved: #51589

changelog: [internal]

With D75140890, there is a guarantee that `startOnRenderCallback_` won't be called after the owning class is destroyed.

There shouldn't be any events flowing through Fabric when the RN instance is torn down. Passing this to eventEmitterListener_ should be safe.

This helps with C++ binary size a little bit.
