Implement QWindow::setWindowIcon

Since QIcon has been moved back to QtGui, QWindow::setWindowIcon can
use it. That way, the api is exactly the same as in QWidgets and one
can deal properly with multi-sized icon.
I added a getter so the api is consistent with QWidget
(Maybe there should be properties for windowIcon and windowTitle)
