[Window] Fix transforms being offset by 0.5x0.5

[Foda]

Description of Change

This PR fixes rotations being offset by 0.5 px in each direction. The property CenterX and CenterY are not normalized (0.0 - 1.0), therefore, setting them offset the transform. Additionally, we already set the RenderTransformOrigin a few lines up.

Could we add an UITest with the example from the video where a button is pressed, an Ellipse is rotated and after finishing the animation verify the Ellipse position? It can be done easily using the VerifyScreenshot method. Example:

maui/src/Controls/tests/UITests/Tests/BorderUITests.cs

Line 37 in 792f1f8

VerifyScreenshot();
