    gmodule: Add support for loading UWP packaged DLLs
    
    LoadLibrary() is not available when building for the Universal Windows
    Platform, which is used for shipping apps to the Windows Store on all
    devices (Windows Desktop, Windows Phone, Surface, XBox, etc).
    
    Apps are not allowed to load arbitrary DLLs from the system. The only
    DLLs they can load are those that are bundled with the app as assets.
    LoadPackagedLibrary() can be used to access those assets by filename.
    
    The function is meant to be a drop-in replacement for LoadLibrary(),
    and the HANDLE returned can be treated the same as before.
