Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49998
We have listeners for EventDispatcher, but we don't have any listener capabilities for synchronous hooks from events on the UI thread.
This proposal adds an affordance for generic event listeners that can be attached by the host platform mounting manager, e.g., to wire events to NativeAnimated event drivers.
## Changelog
