The core only ever outputs through libretro, so drop the ALSA, cubeb, null, OpenAL, OpenSL ES, PulseAudio and WASAPI streams, the backend selection, and the vendored cubeb and OpenAL. SoundStream is now one non-virtual class, implemented by the libretro output in DolphinLibretro/Audio.cpp. Also drop the settings only the backends read (backend, volume, mute, mute on disabled speed limit, latency, WASAPI device) and the volume and mute helpers. The mute-on-fast-forward toggle never had an effect, as the libretro stream ignored volume changes. The GameCube microphone, Wii Speak and Logitech mic keep their libretro microphone path; the unbuilt cubeb capture path and its Windows COM worker thread go. Dolby Pro Logic II decoding (SurroundDecoder, FreeSurround) stays.
