Summary: This diff implements iOS-specific `PlatformRunLoopObserver` (and `MainRunLoopObserver`) that then being glued together with `SynchronousEventBeat` replaces `MainRunLoopEventBeat`, and then same thing glued with `AsynchronousEventBeat` replaces `RuntimeEventBeat`. So, instead of two platform-specific classes we had on iOS (for that needs), now we have only one (that can be reused for a more broad variety of applications). Changelog: [Internal] Fabric-specific internal change. Reviewed By: sammy-SC Differential Revision: D21341998 fbshipit-source-id: fafde4e678770f7fcf9c1ff87acc02812a37e708
