Support for mouse input, not only touch

[ghost]

Windows, Mac, and Linux use mouse input most of the time. We need support for mouse input in MAUI, not only touch. Raising mouse click events as touch events is not good enough.

Can you spec this out @aaabbbcccddd00001111 ?

• enhanced with:
  https://github.com/xamarin/xamarin-forms-samples/blob/main/Effects/TouchTrackingEffect/TouchTrackingEffect/TouchTrackingEffect/TouchActionEventArgs.cs

 public class TouchActionEventArgs { 
...
       TouchDevice Device { get; }
}

public enum TouchDevice {
        Mouse,
        Finger,
        ...
}
