Subject: QQuickItemView: fix crash while doing fast flicking in transitions

The cause was that fast flicking kicked items in and out of viewport,
while in transition, they would abruptly having tracking data structure
, i.e. releasePendingTransition of QQuickItemViewPrivate, got iterator
invalidated. This also helps to resolve QTBUG-44308.

Fixes: QTBUG-76433
