Move numa_emulation codfrom arch/x86 to mm/numa_emulation.c

I am surprised that numa-emulation stayed x86 only for so long. I think
it is useful facility for debugging NUMA scaling and heterogenous memory
topologies. So, glad to see it upleveled.

I recall that s390x had NUMA emulation at some point (primarily to have multiple kthreads be responsible for different physical memory ranges), but it got removed a while ago.
