8304725: AsyncGetCallTrace can cause SIGBUS on M1

[snazarkin]

Hi!

I'd like to backport these changes to get around the WX status uncertainty in AsyncGetCallTrace. The function doesn't use ThreadWXEnable like other VM signal handlers, and writing to the CompiledMethod field results in SIGBUS.

Clean backport. Tested with hostpot tier1 and manually enabled jtreg/serviceability/AsyncGetCallTrace
