(#16330) Update ZAML to latest upstream.

This rebases our internal ZAML on the upstream 0.1.3 release, including the
update to dual-license the code. It then merges back all our changes and
squashes them into place - which, in essence, means bumping the version
number; we already had all the other relevant changes in place.
