bpo-35615: Fix crashes when copying a Weak{Key,Value}Dictionary. (GH-11384) (GH-11785)

Protect dict iterations by wrapping them with _IterationGuard in the
following methods:

- WeakValueDictionary.copy()
- WeakValueDictionary.__deepcopy__()
- WeakKeyDictionary.copy()
- WeakKeyDictionary.__deepcopy__()
(cherry picked from commit 96d37dbcd23e65a7a57819aeced9034296ef747e)
