Summary:
I happened to hit this error a couple times and the issue is that if there are let's say 1000 pending callbacks the error would be triggered 500 times and pretty much crash the app. I think it is reasonable to use warn once here so it only happens once.
## Changelog
[General] [Fixed] - Use `warnOnce` for excessive number of callbacks error
Pull Request resolved: https://github.com/facebook/react-native/pull/26508
Test Plan: Tested by reducing the number of pending callbacks required to trigger the error.
