Add missing NativeEventListener methods to NativeDevSettings (#27838)

Summary:
Since migrating to Turbomodules (8fe04cf) the addMenuItem method crashes because the NativeEventListener methods are missing from the codegen flow type. Added the same methods based on what we do in AppState which is another native module that extends NativeEventListener.
