Add missing invocation of item dispatch listeners when forcing batching of mount items on Android (#45264)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45264

Changelog: [internal]

We added a flag to fix some issues when committing state updates synchronously from the main thread in https://github.com/facebook/react-native/pull/44015 but that implementation was incorrectly not invoking item dispatch listeners after mount.

This adds the missing logic so we can unblock shipping sync state updates.
