libvirt is missing support for some x86 cpu features supported by qemu. This
series adds the missing cpu features to libvirt's feature map and adds a script
to ease the detection of new features in the future.
Support for amx-int8, amx-tile, and amx-bf16 is deliberately not included, as
they were already proposed on the list[1].
