bpo-44184: Fix subtype_dealloc() for freed type (GH-26274) (GH-26290)
Fix a crash at Python exit when a deallocator function removes the
last strong reference to a heap type.
Don't read type memory after calling basedealloc() since
basedealloc() can deallocate the type and free its memory.
_PyMem_IsPtrFreed() argument is now constant.
(cherry picked from commit 615069eb08494d089bf24e43547fbc482ed699b8)
