bpo-46417: Fix race condition on setting type __bases__ (GH-30788) (GH-30789)
Fix a race condition on setting a type __bases__ attribute: the
internal function add_subclass() now gets the
PyTypeObject.tp_subclasses member after calling PyWeakref_NewRef()
which can trigger a garbage collection which can indirectly modify
PyTypeObject.tp_subclasses.
(cherry picked from commit f1c6ae3270913e095d24ae13ecf96f5a32c8c503)
