vcl: mark stock buttons and transfer this to NWF on drawing

Stock buttons like OK/Cancel/Help need sometimes to be drawn
differently than just another button. For this we need to mark
such push buttons as "stock" when building them from a glade file
and transfer this information down to the NWF backend when drawing
the widget.
