Mac zoom support

[janusw]

Carry-over from iniceice88/OxyPlot.Maui.Skia#4 (reported by @KunalKshatriya):

The pan and zoom doesnt work for Mac, I fixed zoom by creating the PlatformTouchEffect for Mac (used the same file as that of iOS).

To make zoom work,

1. I added the following to the PlotController.cs,
   #if MACCATALYST
   this.BindMouseWheel(OxyPlot.PlotCommands.ZoomWheel);
   this.BindMouseWheel(OxyModifierKeys.Control, OxyPlot.PlotCommands.ZoomWheelFine);
   #endif

2. added the Pan gesture recognizer, and raised the onTouchAction

          CGPoint delta = panGestureRecognizer.TranslationInView(view);
          CGPoint point =  panGestureRecognizer.LocationInView(view);
          var touchArgs = new TouchActionEventArgs(1,
             TouchActionType.MouseWheel,
             new Point[] { new(point.X, point.Y) },
             true)
          {
              ModifierKeys = OxyModifierKeys.None
          };
          touchArgs.MouseWheelDelta = (int)((1000 + delta.Y) / 1000);
          onTouchAction(Element, touchArgs);
   

However, it didn't work. Is there something I am missing?
