[GITEA] Avoid WHERE IN for comment migration query

Browse source 
- Rewrite `UpdateCommentsMigrationsByType` to not use `WHERE IN` as
that's a performance diaster for MariaDB, it now use batching to query
the the relevant comment IDs via JOINs (which is not possible in a
UPDATE query for SQLite) and then update them in a seperate query.
- Add unit test.
- Resolves https://codeberg.org/forgejo/forgejo/issues/1856
