Raise informative error when non-object m2o comparison used
An informative error message is raised when an ORM many-to-one comparison
is attempted against an object that is not an actual mapped instance.
Comparisons such as those to scalar subqueries aren't supported;
generalized comparison with subqueries is better achieved using
:meth:`~.RelationshipProperty.Comparator.has`.
Fixes: #5269
