Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/35525 [Changelog][Internal] Adds ability to invoke an async JS callback from a C++ native module, as a task with priority. This will allow native modules to schedule less important calls to JS thread with lower priority. One example use case is feeding collected perf metrics back to JS.
