Calling AsyncGetCallTrace can trigger writing into the PcDescCache. This causes a SIGBUS error when the current thread is not WXWrite mode.
This is due a missing `MACOS_AARCH64_ONLY(ThreadWXEnable wx(WXWrite, Thread::current());)` to ensure that the thread is in this mode during the walking of the thread stack.

This error occurs sporadically but can be easily reproduced using https://github.com/parttimenerd/asgct_bottom with the renaissance dotty benchmark.

I could not reproduce this issue with JFR or async-profiler, but fixing it is simple.

Thanks to Martin and Matthias from my team for helping to debug this bug.
