Tidy up frame rate display in video examples
* Use a Column element to position QML and video frame rate counters.
* When using small-screen layouts, hide frame rate counters when dialogs
or menus are displayed.
* Do not display instantaneous frame rate. If changes in this rate
trigger a repaint, then the rate itself is changed. If the repaint
occurs in less time than the QElapsedTimer resolution, the displayed
instantaneous rate is always zero.
* Add a label, so it is clear which is the QML repaint rate, and which
is the video frame rate.
