In x86 I want to avoid exposing the details of other CPU models
to libvirt because the details depend on machine-type.

But if it is useful for you, I believe the same "qom-properties"
dict could be returned in query-cpu-definitions.

Maybe both? I think it's better to have a separate interface for
querying "what exactly this host supports" and another one for
querying for "what happens if I use -cpu host". In the case of
x86, both are equivalent, but we can't guarantee this on all
