bpo-44184: Fix subtype_dealloc() for freed type (pythonGH-26274)
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.
