Frank Barchard 893eacf9b4 ARGBToY for AVX512
- add ARGBToYMatrixRow_AVX512BW
- refactor SSE and AVX to use Matrix functions, making old functions
  call the new ones.

Zen5 1280x720
Was AVX2   LibYUVConvertTest.ARGBToI444_Opt (1125 ms)
Now AVX512 LibYUVConvertTest.ARGBToI444_Opt (641 ms)

Details by Gemini:
  1. Created 3 new Matrix functions:
    Added ARGBToYMatrixRow_SSSE3, ARGBToYMatrixRow_AVX2, and
    ARGBToYMatrixRow_AVX512BW to source/row_gcc.cc. These take the
    const struct ArgbConstants* c parameter similarly to
    ARGBToUV444MatrixRow_*. The x86 vector instructions dynamically
    calculate the needed values using the properties of the constants
    struct, including using vpmaddwd inside the AVX512 code to offset
    the lack of a native vphaddw.

  2. Replaced Old Functions with Wrappers:
    Modified the existing implementations of ARGBToYRow_SSSE3,
    ARGBToYJRow_SSSE3, ABGRToYRow_SSSE3, ABGRToYJRow_SSSE3,
    RGBAToYRow_SSSE3, RGBAToYJRow_SSSE3, BGRAToYRow_SSSE3 (and their
    _AVX2 equivalents) in source/row_gcc.cc to act as inline wrappers
    calling the new ARGBToYMatrixRow_* functions, passing the right
    matrix parameters (e.g. &kArgbI601Constants, &kArgbJPEGConstants,
    &kAbgrI601Constants).

  3. Added row_any.cc Handlers:
    Added ANY11MC definitions to source/row_any.cc to autogenerate
    ARGBToYMatrixRow_Any_SSSE3, ARGBToYMatrixRow_Any_AVX2, and
    ARGBToYMatrixRow_Any_AVX512BW which safely handles non-aligned
    tails.

  4. Updated include/libyuv/row.h:
    Updated the headers with the proper void declarations for all newly
    generated Matrix and Any_ variants. Also defined
    HAS_ARGBTOYROW_AVX512BW in the CPU macros.

  5. Tested the Implementations:
    Compiled and tested on Linux x86, which resulted in all tests passing
    cleanly. Also successfully completed all Windows 32-bit build checks
    ensuring 32-bit regression prevention without issues.
