8371701: Add ability to set NUMA-affinity for threads

[jsikstro]

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 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

---

• Change must be properly reviewed (1 review required, with at least 1 Reviewer)
