[jdk11u-dev] RFR: 8303215: Make thread stacks not use huge pages [v2]

[Thomas Stuefe]

> Backported for parity with Oracle and as preparation to fix https://bugs.openjdk.org/browse/JDK-8312182.
> 
> Backport is unclean, but the difference is minor. I had to adjust hunks in `os::large_page_init()` since the surrounding coding changed a lot since JDK 11.
