- Implemented `I422ToRGB24Row_AVX2` and `I422ToRGB24Row_AVX512VBMI` in:
- `row_gcc.cc`: Inline assembly for GCC/Clang.
- `row_win.cc`: C++ intrinsics for MSVC (also verified with Clang).
Reduced width alignment requirement: changed from 32-pixel to 16-pixel
alignment in `convert_argb.cc` and `row_any.cc`. This allows the AVX2
path to be used for more common video resolutions.

Add tests of all macros used by libyuv public headers
When a 1 step conversion is added, a 2 step test can compare
the old 2 step method to the 1 step. A 1 step unittest is
also added which compares C to SIMD. Making the 2 step
conversions measure performance of the 2 steps allows the
old 2 step performance to be compared to 1 step.
All macros used in public headers are added to an ifdef test.
Showing them in a unittest allows some diagnostics when
a test is failing.
