Summary:
Let's move the RCTScreenSize and RCTScreenScale calls to the ui thread.

That way, these methods don't do an unsafe sync dispatch to the ui thread, which could deadlock react native.

In the future, once all call-sites are migrated to the ui thread, we will just make these methods assert that they're being called from the ui thread.

Changelog: [Internal]
