Properly handle RR and CMD+M in Bridgeless Mode (#43460)

Summary:
Pull Request resolved: #43460

Currently pressing the menu button (or CMD+M) is broken on Bridgeless mode.
Also pressing RR is not reloading the App.
That's because some Bridgeless API haven't been reimplemented correctly on Android. I'm fixing them here.

Fixes #43451

Changelog:
[Android] [Fixed] - Properly handle RR and CMD+M in Bridgeless Mode
