[NUI] Add GestureDetectorManager (#1895)

- Detect supported gestures.
  : To receive Gesture, you can inherit and implement GestureDetectorManager.GestureListener.
    Then you can implement the necessary callback.

  sample)

            TextLabel backView = new TextLabel
            {
                Size = new Size(300, 300),
                Text = "Back View",
                Position = new Position(50, 70),
                PointSize = 11,
                BackgroundColor = new Color(1.0f, 1.0f, 0.0f, 1.0f),
            };

            mGestureDetector = new GestureDetectorManager(backView, new MyGestureListener());
            backView.TouchEvent += OnBackTouchEvent;

        private bool OnBackTouchEvent(object source, View.TouchEventArgs e)
        {
            Tizen.Log.Error("NUI", $"OnBackTouchEvent {e.Touch.GetState(0)}\n");
            mGestureDetector.FeedTouchEvent(source, e);
            return false;
        }

        class MyGestureListener : GestureDetectorManager.GestureListener
        {
          public override void OnTap(object sender, TapGestureDetector.DetectedEventArgs e)
          {
            Tizen.Log.Error("NUI", $"OnTap \n");
          }

          public override void OnPan(object sender, PanGestureDetector.DetectedEventArgs e)
          {
            Tizen.Log.Error("NUI", $"OnPan \n");
          }

          public override void OnPinch(object sender, PinchGestureDetector.DetectedEventArgs e)
          {
            Tizen.Log.Error("NUI", $"OnPinch \n");
          }

          public override void OnLongPress(object sender, LongPressGestureDetector.DetectedEventArgs e)
          {
            Tizen.Log.Error("NUI", $"OnLongPress \n");
          }
        }
