    soup-enum-types: Make sure items are exported properly
    
    We need to decorate the symbols in the soup-enum-types.h.template with
    GLIB_MKENUMS_EXTERN, and ensure that config.h is included in
    soup-enum-types.c.template, so that the symbols in the generated
    enumeration sources are exported from Visual Studio builds.
    
    This will allow introspection builds to complete successfully on Visual
    Studio.
