Add Popup::setVisible()

This allows nice bindings such as:

    Slider {
        id: slider

        Popup {
            y: -height - 1
            x: -width / 2 + slider.handle.width / 2
            parent: slider.handle
            visible: slider.pressed // <---

            Label {
                text: slider.position.toFixed(2)
            }
        }
    }
