  [HWAsan][NewPM] Handle hwasan like other sanitizers

Move it as an EP callback (-O[123]) or in addSanitizersAtO0.

This makes it not run in ThinLTO pre-link (like the other sanitizers),
so don't check LTO runs in hwasan-new-pm.c. Changing its position also
seems to change the generated IR. I think we just need to make sure the
pass runs.
