8u: Backport 8163363: AArch64: Stack size in tools/launcher/Settings.java needs to be adjusted

[Andrew Dinn]

I would like permission to backport this fix to the
jdk8u-aarch64-shenandoah repo. This fixes the minimum stack size used by
jdk/test/tools/launcher/Settings.java so that it is large enough to
allow the test to pass on AArch64 implementations where it previously
failed.

The backport requires a minor tweak to the original patch as per the
following webrev:
