[WinUI3] LayoutTransformControl crashes when running in AOT mode.

[qian-o]

Describe the bug

When using LayoutTransformControl, running the application after publishing with AOT results in a crash. I will provide a simple WinUI sample program.

You can copy the following code into a test project, publish it, and then run the application.

<controls:LayoutTransformControl>
    <controls:LayoutTransformControl.Transform>
        <RotateTransform x:Name="Rotate" />
    </controls:LayoutTransformControl.Transform>

    <Border Width="20"
            Height="100"
            Background="Green"
            BorderBrush="Black"
            BorderThickness="1" />
</controls:LayoutTransformControl>

public double Angle { get => Rotate.Angle; set => Rotate.Angle = value; }

Expected behavior

Run the AOT published version normally.
