[gtkmm/use-dllexport: 60/62] Meson: Build gtkmm directly for all builds

    Meson: Build gtkmm directly for all builds
    
    The gdkmm and gtkmm headers have GDKMM_API and GTKMM_API at all the needed
    points, so there is no longer need to build gtkmm first as a static library
    for Visual Studio builds.
    
    This also marks the end of using gendef.exe for Meson+Visual Studio builds
