Summary: `SynchronousEventBeat` and `AsynchronousEventBeat` are a cross-platform re-implementation of run loop related parts of `MainRunLoopEventBeat` and `RuntimeEventBeat` (iOS specific classes for now). In the future, they will replace iOS- and Android-specifc event beat classes. Changelog: [Internal] Fabric-specific internal change.
