add recursion check for with_loader_criteria() option

Fixed recursion overflow which could occur within ORM statement compilation
when using either the :func:`_orm.with_loader_criteria` feature or the the
:meth:`_orm.PropComparator.and_` method within a loader strategy in
conjunction with a subquery which referred to the same entity being altered
by the criteria option, or loaded by the loader strategy.  A check for
coming across the same loader criteria option in a recursive fashion has
been added to accommodate for this scenario.

Fixes: #7491
