feature: Support x:FieldModifier Directive (#20)

* Refactoring, decomposition, more unit tests
* Support x:FieldModifier
* Use Xamarin.Forms API for x:FieldModifier
* Use <RestoreSources /> directive, bump Avalonia
* CRLF dance
* Use Fluent theme
* Move Avalonia packages to Directory.Build.props
* Bump test SDK version
