Rename Binding to FabricUIManagerBinding (#46705)

Summary:
Pull Request resolved: #46705

We have multiple classes in React Native Android acting as a binding layer (between C++ and Java, between C++ and JS). Make it more obvious this Binding is for (Android) FabricUIManager and flatten the (now) unused Binding interface.

Changelog: [Android][Removed] BindingImpl is no longer part of the public interface
