[retro-gtk] core: Add Core.set_medias()

[Adrien Plazas <aplazas src gnome org>]

commit 6b653a3b7a246d19032a4227e9726adfdc82ca0a

    core: Add Core.set_medias()
    
    This will be used to simplify loading the games and by extension to
    simplify preparing the cores, exposing less of the internal working.
    
    By extension, simplifying the public API will help porting the library
    to C.
