[OpenMP] Add cpuid leaf 1f topology discovery

This patch adds the new algorithm for topology discovery using cpuid
leaf 1f.  Only the new die level is detected and integrated into the
current affinity mechanisms including KMP_AFFINITY (granularity level
and compact/scatter algorithm), OMP_PLACES=dies, and KMP_HW_SUBSET.
