Implement 32-bit and 64-bit Arm NEON versions (in row_neon.cc and row_neon64.cc) for the 12 remaining row functions that previously fell back to C on Arm: - AR30ToAB30Row_NEON (and AR30ToAB30Row_Any_NEON) - AR30ToABGRRow_NEON (and AR30ToABGRRow_Any_NEON) - AR30ToARGBRow_NEON (and AR30ToARGBRow_Any_NEON) - ARGBAffineRow_NEON - ARGBColorTableRow_NEON - ARGBCopyAlphaRow_NEON (and ARGBCopyAlphaRow_Any_NEON) - ARGBLumaColorTableRow_NEON - ARGBPolynomialRow_NEON (and ARGBPolynomialRow_Any_NEON) - ARGBUnattenuateRow_NEON (and ARGBUnattenuateRow_Any_NEON) - CopyRow_16_NEON (and CopyRow_16_Any_NEON) - MirrorRow_16_NEON (and MirrorRow_16_Any_NEON) - RGBColorTableRow_NEON Add HAS_*_NEON macros, prototypes, _Any wrappers, NEON dispatches in convert.cc, convert_argb.cc, and planar_functions.cc, and enable unit tests in planar_test.cc. Arm row function SIMD coverage is now 164/164 (100%).

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.
