This consolidation standardizes conversion logic, improves code
maintainability, and provides flexible support for various color spaces
(e.g., BT.601, JPEG full
range).
Key Modifications:
- Function Consolidation: Refactored several high-level conversion functions into lightweight wrappers around generic Matrix variants:
- ARGBToI420 → ARGBToI420Matrix
- ARGBToI444 → ARGBToI444Matrix
- ARGBToI422 → ARGBToI422Matrix
- ARGBToNV12 → ARGBToNV12Matrix
- RAWToJ400, RGB24ToJ400 → RGBToI400Matrix
- RAWToI444, RAWToJ444 → RGBToI444Matrix
- 2-Pass Conversions: Updated RGB565ToI420, ARGB1555ToI420, and ARGB4444ToI420 to utilize 2-pass conversions via RGBToI420Matrix.
- Standardization: Refactored ARGBToNV21, ARGBToYUY2, and ARGBToUYVY to use parameterized matrix row functions (ARGBToYMatrixRow,
ARGBToUVMatrixRow).
- Legacy Cleanup: Replaced legacy calls to ARGBToYJRow with the parameterized ARGBToYMatrixRow in the ARGBSobelize helper.
- Internal Integration: Included libyuv/convert_from_argb.h in planar_functions.cc and ensured all new matrix symbols are properly
declared/exported (LIBYUV_API).

- Wired all callers of `ARGBToUVRow_AVX2` and related functions in `source/convert.cc` and `source/convert_from_argb.cc` to dynamically use the `AVX512BW` implementations if the CPU flag indicates AVX-512BW support.
- Optimized AVX-512 code to generate the `-1` multiplier in a single instruction (`vpternlogd`) and reused it across word (`vpmaddwd`) dot products. Handled the resulting negation by replacing a subtraction with `vpaddw` offset adjustment.

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.

The libyuv into Chromium roller is currently broken, see bug 500795092.
This change adds a forward declaration for struct ArgbConstants in
include/libyuv/convert.h. This resolves a -Wvisibility error where the
struct was being declared within a function prototype, making it
invisible outside that scope and breaking automated binding generation
(e.g., for crabbyavif).
Verified building crabbyavif_libyuv_bindings locally and this patch
fixed it.
