Segment throws an error when `FailFastOnErrors` is true.

### Describe the bug

In Windbgx The stack has

* CommunityToolkit_WinUI_Controls_Segmented!CommunityToolkit.WinUI.Controls.SegmentedRns.CommunityToolkit_WinUI_Controls_Segmented_XamlTypeInfo.XamlTypeInfoProvider.set_9_FrameworkElementExtensions_AncestorType+0x5e
* CommunityToolkit_WinUI_Controls_Segmented!CommunityToolkit.WinUI.Controls.SegmentedRns.CommunityToolkit_WinUI_Controls_Segmented_XamlTypeInfo.XamlMember.SetValue+0x59

!Analyze gives

Looking into GetClassInfoFromOtherTypeBox. the runtime class name is null and causes a crash when trying to parse it

No, I'm unable to contribute a solution.

Start with the Segmented control's generated XAML type information, especially XamlTypeInfoProvider.set_9_FrameworkElementExtensions_AncestorType and XamlMember.SetValue from the reported stack. Reproduce in a new WinUI 3 app by enabling FailFastOnErrors in App.Xaml.cs, then compare the launch behavior with and without the control. Done means the app launches without the reported Microsoft.UI.Xaml exception.
