numa: introduce machine callback for VCPU to node mapping
Current default round-robin way of distributing VCPUs among NUMA nodes might be wrong in case on multi-core/threads CPUs. Making guests confused wrt topology where cores from the same socket are on different nodes. Allow a machine to override default mapping by providing MachineClass::cpu_index_to_socket_id() callback which would allow it group VCPUs from a socket on the same NUMA node.
