ABGRToJ420 call ARGBToI420Matrix

- Standardize libyuv ARGB-family (ARGB, ABGR, RGBA, BGRA) to YUV conversion by utilizing the generic MatrixRow architecture and explicit ArgbConstants.
- Consolidated ARGBToI420, ABGRToI420, BGRAToI420, and RGBAToI420 as wrappers for ARGBToI420Matrix.
- Refactored ABGRToJ420, ABGRToJ422, and ABGRToI422 to use generic matrix functions.
- Added matrix-based versions for NV21, I400, YUY2, and UYVY.
- Updated RAW and RGB24 to I420/I422/I444 dispatchers to use MatrixRow logic and explicit constants.
- Fixed parameter swap bugs in ARGBToI422, ARGBToJ422, and ABGRToJ422.
- Fixed a bug in the generic C implementation of matrix row functions ensuring all 4 channels are processed correctly for all ARGB-family formats.
- Moved kShuffleAARRGGBB in row_gcc.cc to the top of the libyuv namespace for visibility.
- Cleaned up redundant format-specific row implementations.

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats for compression.
  • Convert to RGB formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSSE3/AVX2 on x86/x64.
  • Optimized for Neon/SVE2/SME on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
