better naming to enable numa pinning EnableNumaProcessorAffinity , also unit tests and comments review

NumaProcessorAffinity is back to profiles with 'symmetric' value to balance copies across NUMA nodes, one CPU each; explicit CPU IDs pin copies them manually.

fix to have a better EnableNumaProcessorAffinitySymmetric approach

I was covering 3 copies on three 32-core nodes from 96 size. from reviewer request, I added the 6, 8, 12, 13, and 14-copy cases.
