Presently s390x is the only architecture not exposing specific
CPU information via QMP query-cpus. Upstream discussion has shown
that it could make sense to report the architecture specific CPU
state, e.g. to detect that a CPU has been stopped.

With this change the output of query-cpus will look like this on
s390:

    [
      {"arch": "s390", "current": true,
       "props": {"core-id": 0}, "cpu-state": "operating", "CPU": 0,
       "qom_path": "/machine/unattached/device[0]",
       "halted": false, "thread_id": 63115},
      {"arch": "s390", "current": false,
       "props": {"core-id": 1}, "cpu-state": "stopped", "CPU": 1,
       "qom_path": "/machine/unattached/device[1]",
       "halted": true, "thread_id": 63116}
    ]

Maybe worth adding the comment that:

HMP "info cpus" is intentionally not modified, as a later patch will be pruning it down anyways.
