Detailed Description
This attached property manages z-index for stacking overlays relative to each other.
When a popup is about to show, OverlayZStacking object kicks in, searches for the next nearest popup in the QtQuick hierarchy of items, and sets its z value to the biggest of two: current stacking value for its layer, or parent's z index + 1. This way OverlayZStacking algorithm ensures that a popup is always stacked higher than its logical parent popup, but also no lower than its siblings on the same logical layer.
