Frank Barchard 63e54f7374 [libyuv] Add NEON implementations for all remaining C row functions
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%).
