Before, it was often forgotten to pick up new QEMU CPU models and
hard-coding the information in Perl is also not the cleanest way to do
it.
Generate a list of supported models during build of the pve-qemu-kvm
and use that instead. The build will fail when any changes appear, so
they are not missed and can be adapted to.
The qemu-server patch requires the following series by Dominik to be
applied:

Fail the build when the list changes, so that new models can be
picked up selectively and other changes that might require adaptations
are not missed.

thanks, any objection in storing this as pretty-formatted json?
As then the default line-based git diff is making comparisons simpler,
as while word-diff is great, it has it's limits IMO.
No need for a v2 in any case, as that change is easy enough to squash in.
btw. starting to wonder if we should produce an extra architecture "all"
packages for such files, could reduce churn on selective uploads; but I'd
figure that the current rate of change will slow down a bit soon.

No objection, I was considering it too after sending and seeing the very
long line in the patch. But wasn't sure :)

One file for recognized aarch64 CPU flags might still come along in the
context of the custom CPU model edit API/UI. Otherwise, changes to those
files usually come together with switching to a new upstream version.
