RFR: 8371701: Add ability to set NUMA-affinity for threads

[Joel Sikström]

Hello,

This PR adds support for setting the affinity of threads to run on CPUs associated with specific NUMA nodes on Linux. Support for this is needed for [JDK-8371702](https://bugs.openjdk.org/browse/JDK-8371702) to improve performance in the Relocation Phase of ZGC on a NUMA machine.

Testing:
* I've run significant performance testing locally on a NUMA machine and performed functional testing to see that the affinity is actually changed. Affinity of a thread can be inspected on Linux using `taskset -cp <tid>`.
* Running through Oracle's tier1-2
