8340422: ZGC: TestAllocateHeapAt.java should not run with transparent hugepages

[xmas92]

Similarly to JDK-8340146 / #21127 does not work well with transparent hugepages.

Because a machine may be configured in such a way that UseTransperetHugePages option gets ignored, the test driver must also check if it will be. As such I extracted the test/hotspot/jtreg/runtime/os/HugePageConfiguration.java utility into shared test library.

On none linux machines the vm.opt.final.UseTransparentHugePages will be null, but the test checks os.family == "linux" first. I have not observed an issue with the JTREG filter on none linux machines. But will double check that it does not cause an issue.
