[libpas] Fix and re-enable retag-on-scavenge
https://bugs.webkit.org/show_bug.cgi?id=305435
rdar://165772439
Reviewed by Dan Hecht
Previously, we were doing the tag-writes outside of the mutex which
guards the allocation metadata; this was unsafe since it also takes
place strictly after the slot is returned to use, so it's possible for
the memory to be re-allocated while we're tagging it.
