QMP: include CpuInstanceProperties into query_cpus output output
if board supports CpuInstanceProperties, report them for
each CPU thread listed. Main motivation for this is to
provide these properties introspection via QMP interface
for using in test cases to verify numa node to cpu mapping,
which includes not only boards that support cpu hotplug
and have this info in query-hotpluggable-cpus (pc/spapr)
but also for boards that don't not support hotpluggable-cpus
but support numa mapping (virt-arm).
