[gtk/msvc-project-improvements: 3/4] Visual Studio: Make gen-gdkversionmacros-h.py generic

    Visual Studio: Make gen-gdkversionmacros-h.py generic
    
    Rename the script as gen-version-items.py, and so make things more generic and
    usable by other items in the build.  We want to eventually to be able to
    generate the .rc files and the *version*.h files from their *.in counterparts
    using this script.
