Add support for event information in React scheduler tracks in React Native (react#35947)
## Summary This defines the same fiber configuration for RN as used in DOM, so we can expose event timing information in the React scheduler tracks in performance traces. This was unblocked by react#35913 and react#35912. ## How did you test this change? Manually compiled the renderer and tested e2e in FB infra: <img width="1217" height="161" alt="Screenshot 2026-03-03 at 10 10 44" src="https://github.com/user-attachments/assets/6ca1512e-dcaf-49cf-8da9-1c6ae554733a" /> DiffTrain build for [4cc5b7a](react@4cc5b7a)
