Remove bridge mode from RCTComponentData (#59264)

Summary:
Pull Request resolved: #59264

React Native only runs bridgeless now, so the bridge-mode code path is dead. Remove it, collapse the dual view-manager properties into a single strong reference, and route events through the already-injected dispatcher.
