gh-122559: Synchronize C and Python implementation of the io module about pickling (GH-122628)

Browse source 
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.
