[NUI] Add DisallowInterceptTouchEvent (#2109)

If child view doesn't want the parent's view to intercept the touch, you can set it to true.
 for example :
    parent.Add(child);
    parent.InterceptTouchEvent += OnInterceptTouchEvent;
    View view = child.GetParent() as View;
    view.DisallowInterceptTouchEvent = true;
 This prevents the parent from interceping touch.
