Removes non-matrix implementations for RGB24, RAW, RGB565, ARGB1555, and ARGB4444 conversions. Introduces RGBToYMatrixRow, RGBToUVMatrixRow, and equivalent functions for 16-bit and 24-bit formats. These functions utilize a 2-step conversion internally (to ARGB, then to YUV) inside row_common.cc for C, AVX2, and NEON, allowing the high-level convert.cc logic to execute in a single pass using ArgbConstants.
