M420 is a row biplanar variation of NV12 supported on Microsoft webcams.
The code was hardcoded to bt.601 and should be jpeg, but the format is
very old and rare. Is a variation on NV12, so if someone needs it, it
can be re-implemented easily.

Call a row function for each row, based on ARGBToI400 code.
But implement row functions as 2 step conversion. Adds the
row functions:
RAWToYJ, RGBToYJ, SSSE3 and AVX2 versions, and Any versions.
The smaller row buffer is more cache friendly on large images.
The max cache size can be configured, and is currently:
// Maximum temporary width for wrappers to process at a time, in pixels.
And the row buffer is
SIMD_ALIGNED(uint8_t row[MAXTWIDTH * 4]);
So 8192 bytes are used for the row buffer, leaving the rest for source
and destination buffers.

Convert planar 8 bit formats to planar 16 bit formats.
Includes msan fix for Convert8To16Row_Opt unittest.
I420 is YUV bt.601 8 bits per channel with 420 subsampling.
I010 is YUV bt.601 10 bits per channel with 420 subsampling.
I is color space - bt.601. The function does no color space
conversion so H420ToI010 is aliased to this function as well.
0 = 420 subsampling. The chroma channels are half width / height.
10 = 10 bits per channel, stored in low 10 bits of 16 bit samples.
