Fix QGraphicsScene::update() performance
A previous fix has caused a performance degradation while adding a
check for avoiding adding duplicated rectangles to the update list.
This patch fixes it by using a std::set instead of a QList, avoiding
duplication while using an O(log N) operation, instead of the O(N)
used before.
Fixes: QTBUG-77952
