Migrate FlutterRestorationPlugin, FlutterTextureRegistryRelay, FlutterScreenAndSceneIfLoaded to ARC (#51984)

Smart pointers support ARC as of https://github.com/flutter/engine/pull/47612, and the unit tests were migrated in https://github.com/flutter/engine/pull/48162.

Migrate `FlutterRestorationPlugin`, `FlutterTextureRegistryRelay`, and `UIViewController+FlutterScreenAndSceneIfLoaded` from MRC to ARC.  These files do not themselves import any MRC files, making them leaf nodes in the dependency graph of MRC files.  

Doing a few at a time to make the dependency graph manageable, and to easily revert if this causes retain cycles or other memory management issues.
