Frank Barchard 9f13b2814d add RGBToYMatrixRow_AVX2 
Adds RGBToYMatrixRow_AVX2 which reads 24 bit RGB values by reading 3 vectors instead of 4 and permutes them into 4 ARGB vectors before conversion.
Also adds RGBToYMatrixRow_Opt and RGBToYMatrixRow_2Step_Opt to convert_argb_test.cc to benchmark and compare the direct AVX2 conversion vs a 2-step approach.

./libyuv_test '--gunit_filter=*RAWToJ400_Opt' --libyuv_width=1280 --libyuv_height=720 --libyuv_repeat=10000 --libyuv_flags=-1 --libyuv_cpu_info=-1

AMD Zen 5
Was LibYUVConvertTest.RAWToJ400_Opt (757 ms)
Now LibYUVConvertTest.RAWToJ400_Opt (699 ms)

Intel Skylake
Was LibYUVConvertTest.RAWToJ400_Opt (1705 ms)
Now LibYUVConvertTest.RAWToJ400_Opt (1426 ms)
