Fix GRANTED BY support in REVOKE ROLE statements

Enterprise / PostgreSQL - Daniel Gustafsson [postgresql.org] - 26 November 2021 13:02 UTC

Commit 6aaaa76bb added support for the GRANTED BY clause in GRANT and REVOKE statements, but missed adding support for checking the role in the REVOKE ROLE case. Fix by checking that the parsed role matches the CURRENT_ROLE/CURRENT_USER requirement, and also add some tests for it. Backpatch to v14 where GRANTED BY support was introduced.
