chore: remove the gridelements migration and the address check table

The grids are migrated in production, and the production database is the
master that is never replaced by a TYPO3 10 dump, so ep:migrate-gridelements
has nothing left to do; its tx_gridelements_* columns are dropped. The
address check forms are gone (pages removed), and so is the table that
stored their submissions: personal data that has not been processed since
2019.

The tables and columns themselves are dropped by hand: extension:setup only
adds and changes.
