[profiler] Move away from UnboundedQueue to LockedQueue for regular events.

[profiler] Move away from UnboundedQueue to LockedQueue for regular events.

Replaces the UnboundedQueue (SP/SC) with LockedQueue (MP/MC). This is necessary
as we can have multiple tasks (on multiple platform threads) reporting code move
events.

Note that the sampling queue is not affected by this change.
