Add ComputeCumulativeSumRow_AVX2, CumulativeSumToAverageRow_AVX2, ComputeCumulativeSumRow_NEON, and CumulativeSumToAverageRow_NEON to accelerate ARGBBlur and ARGBComputeCumulativeSum on x86_64 and aarch64. Update ARGBBlurSmall_Opt to benchmark 320x180 with radius 1 and use a circular cumsum buffer of height radius * 2 + 2 in TestBlur.
