    GResource compiler: Prefix static [con|de]strutors with c_name
    
    When attempting to test Windows support for building libadwaita, since we are
    using multiple GResource files, one would hit linker errors where multiple
    definitions of the following symbols have been defined, when
    glib-compile-resources was invoked without manual register:
    
    resource_constructor_wrapper
    resource_destructor_constructor
    _arrayresource_constructor
    _arrayresource_destructor
    
    In order to avoid that, just prefix the definitions of resource_constructor
    and resource_destructor, like what we do when --manual-register is used, with
    what we pass in with --c-name so that we ensure that we do not end up in such
    name collisions.
