Add type tests for AnimatedRef and fix Animated Components regression (…

…#5308)

Requires #5320.

## Summary

I induced a regression accidentally in #5031 regarding FlatList. 

This PR:
- fixes this regression,
- improves the type structure of other components,
- adds a new test suite to detect such mistakes in the future.

It also automatically fixes failing future RN version typecheck CI.

## Test plan

All the new & old tests should work.
