In the C implementation, remove __reduce__ and __reduce_ex__ methods that always raise TypeError and restore __getstate__ methods that always raise TypeErrori.

This restores fine details of the pre-3.12 behavior and unifies both implementations.

Are there checks for the TypeError when it's not subclassed?

The current behavior is inconsistent, so I have not add tests for it.
