numa: mirror cpu to node mapping in MachineState::possible_cpus

Browse source 
Introduce machine_set_cpu_numa_node() helper that stores
node mapping for CPU in MachineState::possible_cpus.
CPU and node it belongs to is specified by 'props' argument.

Patch doesn't remove old way of storing mapping in
numa_info[X].node_cpu as removing it at the same time
makes patch rather big. Instead it just mirrors mapping
in possible_cpus and follow up per target patches will
switch to possible_cpus and numa_info[X].node_cpu will
be removed once there isn't any users left.
