qapi/machine.json: Add cluster-id

Browse Source 
This adds cluster-id in CPU instance properties, which will be used
by arm/virt machine. Besides, the cluster-id is also verified or
dumped in various spots:

  * hw/core/machine.c::machine_set_cpu_numa_node() to associate
    CPU with its NUMA node.

  * hw/core/machine.c::machine_numa_finish_cpu_init() to record
    CPU slots with no NUMA mapping set.

  * hw/core/machine-hmp-cmds.c::hmp_hotpluggable_cpus() to dump
    cluster-id.
