    gjs/global.cpp: Fix linking on Visual Studio builds
    
    It seems that Visual Studio does not like using external variables from a
    static constexpr construct in terms of linking to a DLL, so fix this by
    using a global constant that pulls in the external (constant) variable that we
    are using, and use that global constant in our static constexpr construct,
    which will fix linking on Visual Studio.
