[TASK] Remove TCA definitions for pre FAL fields

There are some overrides in the CMS extension that provide the old
TCA for the image and media fields of tt_content and
pages_language_overlay tables. These apply if the compat version
is set to 6.0 and and FAL upgrade wizard is not yet run.

Those are removed now as we only support migrations from one LTS
to the next LTS.
