Rework XAML compilation targets (#17539)

* Added BuildTests projects

* Added VerifyXamlCompilation build target

* Use TargetsTriggerByCompilation for XAML compilation

* Add *.binlog to gitignore

* VerifyXamlCompilation target: set NuGetPackageRoot

* Ensure WpfHybrid build test uses two markup compilation passes

* Fail build tests restore immediately if AvaloniaVersion isn't set

* Fix "could not extract MVID" for up-to-date builds

* Run VerifyXamlCompilation on CI

* Add FSharp build test
