Describe the bug

When including Microsoft.Windows.SDK.BuildTools transitively - for example you have a reference to the WASDK - it does not bring in the Microsoft.Windows.SDK.BuildTools targets. This is because the NuGet only has a build folder and is missing the buildTransitive folder.

This is why the package needs to be explicitly referenced in the WASDK templates:

Steps to reproduce the bug

1. File | New | WinUI app
2. File | New | WinUI library
3. Add a reference from the app to the librry
4. Remove the package reference to Microsoft.Windows.SDK.BuildTools AND Microspft.WindowsAppSDK from the app project
5. dotnet build
6. Observe the build fails if you do not have VS installed :)
