fix: add GrantStmt method to handle REVOKE EXECUTE ON FUNCTION statements

- Add GrantStmt method to pass objtype context to ObjectWithArgs for proper objfuncargs generation
- Fix original-upstream-create_operator test by correctly handling GrantStmt with OBJECT_FUNCTION objtype
- Ensure REVOKE/GRANT statements on functions get proper objfuncargs transformation
- Progress: multiple key tests now passing including misc-cascades, original-comment, and create_operator
