Compress Kernel Firmwares to reduce on disk size

== Detailed Description ==
Since the linux 5.3 kernel there has been support for loading firmware
from xz compressed firmware. The upstream linux-firmware respository
is now over 900Mb, not including other kernel firmware that are in
Fedora but come from other sources. By compessing the firmware with
"xz -C crc32", the only option currently supported in the kernel, we
can reduce the ondisk size of the firmware by almost half.
I vaguely recall that there was some effort to add zstd support to
compress kernel stuff. Could we consider using that for this instead
of xz? Or is that still only for kernel modules?
