Summary:
Reland https://github.com/facebook/react-native/issues/15611 and added the gcc warning that was different from fb internal config. The original PR missed the static keyword for the `RCTNormalizeAnimatedEventName` function which triggered the gcc warning internally but not with the OSS xcode config.
When calling a prop of type `RCTDirectEventBlock` or `RCTBubblingEventBlock` it uses a completely different code path than events using `[RCTEventDispatcher sendEvent:]` and those were not dispatched to the `RCTEventDispatcherListener`s. We also do some event name normalization which caused issues between the JS and native event names. To fix that I simply remove the parts we normalize from the event key.
## Changelog:
[iOS] [Fixed] - Support events using RCT{Direct|Bubbling}EventBlock
Pull Request resolved: https://github.com/facebook/react-native/pull/25317
Test Plan: Added a Slider (it uses RCTBubblingEventBlock for its onValueChange event) that can control a native animated value in RNTester to reproduce the bug and made sure this diff fixes it.
