[gnome-games/wip/exalm/uid: 4/16] retro-runner: Simplify construction

[Alexander Mikhaylenko <alexm src gnome org>]

commit c1c98bc288b6ffd5e8881ca0a0fdd2c6e05e7316

    retro-runner: Simplify construction
    
    Remove RetroRunnerBuilder, restore separate constructors. Since everything
    other than RetroCoreSource or Retro.CoreDescriptor is now contained within
    Game, they can be simplified down to 2 arguments each. Pass
    InputCapabilities via a property.
