CI: Add new workflow to create all casks [skip-ci]

Now we can create the casks of some specific release ('latest' in this
case) at will, based purely on the artifact files and on nothing in the
repo. We do not even need to fetch the repo.

This is still some kind of WIP, because we do not have the secrets and
not even a proper homebrew fork in our organization.
