Add closing process when tapping the outer area of ​​Popup

[cat0363]

This PR resolves the issue where the Popup cannot be closed when the CanBeDismissedByTappingOutsideOfPopup property is true and you tap an area within 10px around the Popup.

Description of Change

Dialog, which is the base of Popup, has areas around it that do not respond to taps on Android.
Handle the touch event and intentionally call the Popup's close process when the outside of the Popup is tapped.
Below are the changes.

[src\CommunityToolkit.Maui.Core\Views\Popup\MauiPopup.android.cs]

	public override bool OnTouchEvent(MotionEvent e)
	{
		if (VirtualView is not null)
		{
			if (VirtualView.CanBeDismissedByTappingOutsideOfPopup &&
				e.Action == MotionEventActions.Up)
			{
				if (Window?.DecorView is AView decorView)
				{
					float x = e.GetX();
					float y = e.GetY();

					if (!(x >= 0 && x <= decorView.Width && y >= 0 && y <= decorView.Height))
					{
						if (IsShowing)
						{
							OnDismissedByTappingOutsideOfPopup(this);
						}
					}
				}
			}
		}

		if (this.IsDisposed())
		{
			return false;
		}
		else
		{
			return base.OnTouchEvent(e);
		}
	}

The above code calls the OnDismissedByTappingOutsideOfPopup method when the tapped coordinates are outside the Popup.
The return value of OnTouchEvent is separated by an If statement, because if you call OnDismissedByTappingOutsideOfPopup, MauiPopup will be disposed of, and an ObjectDisposedException will occur when base.OnTouchEvent(e) is called.

I didn't know how to write it smartly.
If there is a smarter way to write it, could you please refactor it.

Additional information

Below are the verification results.
To make it easier to see where the taps are, I turned on "Show taps" in the Android developer options.

[CanBeDismissedByTappingOutsideOfPopup : true]

If the CanBeDismissedByTappingOutsideOfPopup property is true, you can see that tapping within 10px around the Popup will close the Popup.
