bpo-40521: Make context free list per-interpreter (GH-20644)
Each interpreter now has its own context free list:
* Move context free list into PyInterpreterState.
* Add _Py_context_state structure.
* Add tstate parameter to _PyContext_ClearFreeList()
and _PyContext_Fini().
* Pass tstate to clear_freelists().
