[jdk11u-dev] RFR: 8262894: [macos_aarch64] SIGBUS in Assembler::ld_st2 [v2]

[Vladimir Kempik]

> Pleas review this backport to jdk11u-dev.
> It's one of few follow up fixes for jep-391 backport.
> This adds missing WX transition to jni_DestroyJavaVM_inner and jni_DetachCurrentThread
> Not applying clean due to context code difference in chunk 2.
> In JDK17 it's  - ThreadStateTransition::transition()
> in JDK11 it's - ThreadStateTransition::transition_and_fence()
