feat(console): add the standalone Dolphin emulator

The libretro dolphin core lags upstream on compatibility in the same way
LRPS2 does, so install pkgs.dolphin-emu next to pkgs.pcsx2 and run
GameCube and Wii titles through it. The cores stay for the sake of a
single frontend and a shared save/state layout.
