Generate strongly typed resources as part of build

[bergmeister]

PR Summary

At the moment one needs to update the Strings.Designer.cs files when new entries are adding to String.resx files because the .NET CLI cannot generate them by default, which makes it hard for developers that do not use Visual Studio but VS-Code or just CLI. However, there is a way to make this work and generate the strongly resource as part of the build and make it work for CLI, VS-Code (when it does a restore) and Visual Studio, which uses MSBuild, see here: https://github.com/dotnet/msbuild/issues/4751

@bergmeister if you could solve the merge conflict that would be great.
