Initial aarch64 compose enablement on primary koji
This is the initial enablement for aarch64 on rawhide. It adds:
* repos/net install for Everything/Cloud/Server/Workstation
* Server DVD installs
It also cleans up the config a little, remove s390(x) multilib, orders
architectures alphabetically so they're consistent and a litte easier to
read thoughout variants-fedora.xml.
What is still outstanding:
* Add configs for slicing up the compose output and sync out to mirror locations
* Cloud and Docker images
* Disk images
The first item will be a new PR, the later two are being worked upon.
