implement FromLinter for UPDATE, DELETE statements
Implemented the "cartesian product warning" for UPDATE and DELETE
statements, those which include multiple tables that are not correlated
together in some way.
Fixed issue where :func:`_dml.update` construct that included multiple
tables and no VALUES clause would raise with an internal error. Current
behavior for :class:`_dml.Update` with no values is to generate a SQL
UPDATE statement with an empty "set" clause, so this has been made
consistent for this specific sub-case.
Fixes: #9721
