feat: support DROP ROLE
Summary
Support DROP ROLE in SQL API.
These changes were lost during CREATE/DROP ROLE MR merge. I propose to change f4458913 commit message to "CREATE ROLE".
Ensure that
-
New code is covered by tests -
API is documented -
Changelog is up to date -
(if Lua API changed) Lua API version is bumped inluamod.rs
-
(if necessary) A follow-up doc issue is created in picodata/docs and linked here
