Add MangoHud module and enable it on hosts

Introduce a new `mangohud.nix` module with sensible defaults, import it in `modules/home/default.nix`, and add a `mangohud.enable` flag to the host configurations (enabled for desktop and laptop, disabled for the default host). Comment out the default Gamescope arguments in `modules/core/steam.nix` and add a reference command line that includes the MangoHud flag.
