disable raise sql for the delete cascade
Towards maintaining consistency with unit-of-work changes made for
:ticket:`5984` and :ticket:`8862`, both of which disable "lazy='raise'"
handling within :class:`_orm.Session` processes that aren't triggered by
attribute access, the :meth:`_orm.Session.delete` method will now also
disable "lazy='raise'" handling when it traverses relationship paths in
order to process the "delete" and "delete-orphan" cascade rules.
Previously, there was no easy way to generically call
:meth:`_orm.Session.delete` on an object that had "lazy='raise'" set up
such that only the necessary relationships would be loaded. As
"lazy='raise'" is primarily intended to catch SQL loading that emits on
attribute access, :meth:`_orm.Session.delete` is now made to behave like
other :class:`_orm.Session` methods including :meth:`_orm.Session.merge` as
well as :meth:`_orm.Session.flush` along with autoflush.
Fixes: #9549
