contrib/buildsystems: support modern Visual Studio project definitions

The .sln/.vcproj files were used to define projects up until Visual
Studio 2008, but starting with Visual Studio 2010 the project
definitions are stored in .sln/.vcxproj files (which can also be used
by the MSBuild system).

Let's just copy-edit the generator of the .vcproj files to a new
generator that produces .vcxproj files directly, without forcing Visual
Studio to upgrade the project definitions.
