This PR adds support for UWP on modern .NET, by adding new UWP projects targeting .NET 8 and packaging them in a new TFM folder in the Microsoft.Xaml.Behaviors.Uwp.Managed NuGet package. Virtually no code changes are required (and we also get all the trim/AOT support for free from #255). The .csproj files could be simplified further, but keeping them the same as the ones for WinUI so that things are easier to maintain (fewer differences between the two flavors).
[!NOTE]
Can only build locally for now as it requires previews of Visual Studio, MSBuild, the XAML Compiler and the .NET SDK.
