Added QWindow::Visibility convenience API to QWindow.

This finally makes it possible to make windows fullscreen etc from
QML by doing "visibility: Window.FullScreen". I don't see any reason
from not having the API at the QWindow-level instead of at the
QQuickWindow-level since this way it can benefit other use cases too.
