Repaired a deprecation warning class decorator that was preventing key objects such as :class:`_engine.Connection` from having a proper ``__weakref__`` attribute, causing operations like Python standard library ``inspect.getmembers()`` to fail. Fixes: #8115 Change-Id: Ifd0bc2325fb9dc9e1431998c308b7fc081968373
