Queue applySyncTransaction calls when there is active BLAST sync

We currently queue applySyncTransaction in WM Shell, but it doesn't sync
with Shell transition collection. However, when both happen, it may
cause issue because the BLASTSyncEngine currently only support 1 sync at
a time.

Move the Shell transition queue to WindowOrganizerController as we only
queue organizer sync. Unfortunately, unlike organizer sync that is in
one WCT, we can't prevent any core-initiated transition.

We don't expect it to happen, but if it does, we need to handle them
case by case.
