gh-76785: Drop PyInterpreterID_Type (gh-117101)

Browse source 
I added it quite a while ago as a strategy for managing interpreter lifetimes relative to the PEP 554 (now 734) implementation.  Relatively recently I refactored that implementation to no longer rely on InterpreterID objects.  Thus now I'm removing it.
