Benchmark on Icelake Xeon Now AVX512BW: [ OK ] LibYUVConvertTest.ARGBToNV12_Opt (1723 ms) Was AVX2: [ OK ] LibYUVConvertTest.ARGBToNV12_Opt (2144 ms) - Added `ARGBToUVMatrixRow_AVX512BW` implementation in `source/row_gcc.cc`. - Added corresponding `ARGBToUVRow_AVX512BW` and `ABGRToUVRow_AVX512BW` functions. - Added unaligned wrappers `ARGBToUVRow_Any_AVX512BW` and `ABGRToUVRow_Any_AVX512BW` in `source/row_any.cc`. - Updated `source/row_any.cc` to correctly size `vin` and `vout` buffers for AVX512BW width and adjusted the `ANY12MS` and `ANY12S` macros to handle `MASK=63`. - Updated `include/libyuv/row.h` with the required AVX512BW headers and definitions, scoped appropriately. - 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.
