numa: make hmp 'info numa' fetch numa nodes from qmp_query_cpus() result

HMP command 'info numa' is the last external user that access
CPUState::numa_node field directly. In order to move it to CPU
classes that actually use it, eliminate direct access and use
an alternative approach by using result of qmp_query_cpus(),
which provides topology properties CPU threads are associated
with (including node-id).
