audio: Remove 5.1->X SIMD converters, add SSE mono->stereo. The 5.1 versions didn't use the new algorithm, and making that new algorithm work took so many permutes that it was significantly slower than just using the scalar versions. However, mono-to-stereo is an extremely common conversion, and it's trivial to accelerate it with plain SSE, so that was added!
