[heguanhui]

What problem does this PR solve?

Issue Number: close #xxx

Problem Summary: Currently, dropping row policies for multiple roles requires executing DROP ROW POLICY statement for each policy individually, which is cumbersome when a role has many policies. This PR adds a new syntax DROP ROW POLICY FOR ROLE role1, role2, ... to drop all row policies bound to the specified roles in one statement.

Support new syntax: DROP ROW POLICY FOR ROLE role1, role2, ... to drop all row policies bound to specified roles in batch.
