[jdk11u-dev] RFR: 8234930: Use MAP_JIT when allocating pages for code cache on macOS [v5]

[Vladimir Kempik]

> Hello, here is alternative backport of 8234930 to jdk11u.
> Very minimalistic change for platforms other than macos, just one unused argument.
> We have used this patch in zulu11 for more than a year now and found no issues with it on macos and other platforms.
>
> Technically it's mostly the same as previous (3patch) version but has no prerequests.
