do not allow non-cache-key entity objects in annotations

Fixed critical caching issue where combination of :func:`_orm.aliased()`
:func:`_sql.case` and :func:`_hybrid.hybrid_property` expressions would
cause a cache key mismatch, leading to cache keys that held onto the actual
:func:`_orm.aliased` object while also not matching each other, filling up
the cache.

Fixes: #9728
