@lang/openjdk11: Workaround for the VM dying on Apple Silicon chips

See the patch for threadWXSetters.inline.hpp for details. I rebuilt the
bootkit for aarch64 with new patches applied. This may cause some
performance regression on Cortex series, but as I stated in the patch
comment, relying on assumptions made on implementation details of chips is
fundamentally unsound, and that's why it didn't work on Apple Silicon in
the first place.

Also backported fixes regarding floating point arithmetics that appeared in
OpenJDK 22.
