lutris: add module (#6964)

Add any number of wine packages
    Add any number of proton packages
    Link runners directly from nix instead of using lutris.
    Specify the steam package lutris should use.
    Extra packages passed to lutris (mainly since it's often missing essential things, such as umu-launcher)
