[Auth-UI] [v10.0.0-beta03] Untranslatable strings

[jliumo]

Methods in the com.firebase.ui.auth.configuration.auth_provider package emit hardcoded English strings, like updateAuthState(AuthState.Loading("Signing in user...")). This would be reasonable for internal messages; however, FirebaseAuthScreen shows them to the user in LoadingDialog and dialogController.CurrentDialog(), which are not configurable.
