[!!!][TASK] Remove sys_domain redirect functionality

The existing functionality of sys_domain database records that redirect to a
different target has been migrated into the new "redirects" core extension.

An upgrade wizard ensures that old (and even deleted) sys_domain records
with a redirect target (database field "redirectTo") are properly migrated into
the redirects extension.

The following database fields have been dropped:
- sys_domain.redirectTo
- sys_domain.redirectHttpStatusCode
- sys_domain.prepend_params

These values are not evaluated anymore in the TYPO3 Frontend.
