Remove Windows and X11 from src/widgets/platforms.
This is dead code, unused with QPA in place, so remove it to avoid confusion caused through grepping for class names existing in both old and new places. Mac code is left in place for now, as some of it is still in use. Change-Id: Ia82cd5bbabe71285ca997f79d8fd9c0504e32c28 Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com>
