Add some docs that explicitly mentions how we handle cycles in the tree
This was reported for QGraphicsAnchorLayout, but affects all
QGraphicsLayout subclasses. However, since it is not even handled
properly in QGraphicsItem::setParentItem() it should be fine that we
don't try to deal with this issue. Thus, the layouts are "consistent"
with graphics items when it comes to detection of cycles in the tree.
