Detect dirty child window stacking order without recursing all items
Recursing all items was causing a high CPU utilization in scenarios
with deep and wide item trees (>10k items).
We can limit the search for a dirty item with ChildrenStackingChanged
to the list of dirty items.
For a synthetic benchmark this reduces the iteration time fro 0.60 ms
to 0.13 ms.
Pick-to: 6.7 6.8
Fixes: QTBUG-126673
