x86-64, NUMA: Unify emulated apicid -> node mapping transformation
NUMA emulation changes node mappings and thus apicid -> node mapping
needs to be updated accordingly. srat_64 and amdtopology_64 did this
separately; however, all the necessary information is the mapping from
emulated nodes to physical nodes which is available in
emu_nid_to_phys[].
Implement common __apicid_to_node[] transformation in numa_emulation()
and drop duplicate implementations.
