Add popup support to QWaylandQuickCompositor with the wl shell.

When the shell surface emits the QWaylandShell::setPopup signal the
QWaylandQuickWlShellSurfaceItem will move it self into its popup-parent,
and also remove all transforms (rotation, scaling, etc.), our new
parent already have the same transforms set.

During the time a popup is active it installs a filter
which handles the closing of popups if the user clicks
outside the popup. This requires that the background item of the
compositor accepts mouse press.
