QQuickDrawer: allow resizing and positioning

Make QQuickDrawer re-use QQuickPopup's reposition() implementation.
This way QQuickDrawer gains support for proper positioning and margins
"for free". Now it is possible to place Drawer below the window header,
for instance:

    import QtQuick 2.0
    import QtQuick.Controls 2.0

    ApplicationWindow {
        id: window
        visible: true

        header: ToolBar { }

        Drawer {
            y: header.height
            width: window.width * 0.6
            height: window.height - header.height
        }
    }

[ChangeLog][Controls][Drawer] Made it possible to control the vertical
position of a horizontal drawer, and vice versa. This allows placing
a drawer below a header/toolbar, for instance.
