Add NUMA and thread affinity support for Unix (#10938)

* Add NUMA and thread affinity support for Unix

This change adds new PAL functions for NUMA and thread affinity support
for Unix and also enables related code in GC and VM for FEATURE_PAL.

It doesn't reflect the limits imposed by CGROUPS on systems with
CGROUPS enables yet.
