[Sanitizer] Call StackDepotStopBackgroundThread() on all platforms

[yln]

Summary

Call __sanitizer::StackDepotStopBackgroundThread() from
__sanitizer_sandbox_on_notify() on all platforms.

This should be gated on stack depot code availability, but not on
platform.

rdar://86347037

[yln]

Fixes the failing test compress_stack_depot.cpp on Darwin.

[yln]

Guard with #if !SANITIZER_GO.

Just noticed this review after pushing 80c95bbdf359c54abaeacdbcc070b7b5d3b25b6a
Almost the same but we can't do that on Windows

[yln]

Fixed by 80c95bbdf359c54abaeacdbcc070b7b5d3b25b6a
