[Bug] +Fix. Path.Data crashing when geometry has a PolyLineSegment with 0 point

[softlion]

Description

When Path.Data is set to a geometry containing a PolyLineSegment with 0 point, it crashes

Looking into source line 93 of GeometryExtensions.cs:

https://github.com/xamarin/Xamarin.Forms/blob/5.0.0/Xamarin.Forms.Platform.iOS/Extensions/GeometryExtensions.cs

                        else if (pathSegment is PolyLineSegment)
                        {
                            PolyLineSegment polylineSegment = pathSegment as PolyLineSegment;
                            PointCollection points = polylineSegment.Points;

                            for (int i = 0; i < points.Count; i++)
                                pathData.Data.AddLineToPoint(transform, points[i].ToPointF());

                            lastPoint = points[points.Count - 1];
                        }

If polylineSegment.Points.Count is 0, then the last line crashes (points[points.Count - 1];)
