This moves the no-channel-base check into the prepare script to exit
early and prevent all of CI to run against those branches. We also
provide better output by posting a "Changes Requested" review, using the
existing infrastructure from the old cherry-picks check.
The review will be dismissed automatically once the branch has been
corrected, because the commits check will run and do it.
