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.
For SSSE3 version:

based on counter sizes. The higher level calls the low level
in blocks that avoid overflow and then accumulators in int64.
This test compares the results of the low levels to the high

count is correct for any specified size.
The the size is very large, the result is expected to be
