Move DOM APIs to native module (#43512)

Summary:
Changelog: [internal]

This moves all the new methods that were added to implement the DOM traversal and layout APIs (as per this RFC: react-native-community/discussions-and-proposals#607) to a separate C++ native module to avoid bloating the UIManager interface, initialize lazily, provide automatic caching of methods, simplify the API for implementors, etc.
