Venice][Android] Migrate ReactModalHostView to use BridgelessReactContext

Summary:
- Use ThemedReactContext explicitly to reduce confusion, "addLifecycleEventListener()" and "removeLifecycleEventListener" should be forced to call on ThemedReactContext
- Migrate "getNativeModule" and "handleException" calls from ThemedReactContext to ThemedReactContext.getReactApplicationContext

Changelog:
[Android][Changed] - Use ThemedReactContext explicitly to reduce confusion
