History
Frank Barchard 4aacbbdfb4 Refactored RGB/RAW to YUV color conversion functions to use generic Matrix-based functions parameterized by ArgbConstants. 
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).
