LIBYUV_SSSE3_ONLY was for functions that have SSE2 and SSSE3 but are compiling for SSSE3, so SSE2 will never be used.
Remove the SSE2 implementation of ARGBSHUFFLEROW_SSE2 and rely on SSSE3.

YUV 411 is very uncommon format. Remove support.
Update documentation to reflect that 411 is deprecated.
Simplify tests for YUV to only test with the new side by side YUV but keep old 3 plane test around with a macro for now.

The old guard only checked for defined(_M_X64) which is defined by mingw64. Add a test for defined(_MSC_VER) which is defined for clangcl and visual c but not mingw. mingw should use row_gcc.cc for both 32 and 64 bit.

U contributes to B and G. V contributes to R and G.
By swapping U and V, they contribute to the opposite channels. Adjust the matrix so the U contribution is in the matrix location such that it till contribute to the
new B channel and vice versa.
This allows ABGR versions of YUV conversion to use the same low level code as ARGB, just using a different matrix and swapping U and V pointers.
As a result the existing I444ToABGRRow functions are no longer needed and are removed.
Previously this function was only Intel AVX2 optimized for Windwos. Now it is also optimized for Arm and GCC.

yuv constants for bt.601 were previously ported to neon64, as well
as the code to respect other color spaces. But the jpeg and bt.709
colour conversion constants were still in armv7 form. This changes
the constants for aarch64 builds to be compatible with the code.
yuv constants are now passed as const *
Remove Yvu constants which were used for older version on nv21 but not new code.

Low level for NV21ToARGB written to accept yuv matrix used by
other YUV to ARGB functions.
Previously NV21 was implemented for Windows using NV12 with a different
matrix that swapped U and V. But the Arm version of the low level does
not allow the matrix U and V contributions to be swapped.
Using a new low level function that reads NV21 and uses the same
yuvconstants as other YUV conversion functions allows an Arm port of
this function.
