Frank Barchard 378bc91324 [libyuv] Multi-platform ScaleUVAddCols3 for ScaleUVBox at 3x 
Based on Philipp Hancke's AVX2 column kernel for ScaleUVBox at 3x
(https://crrev.com/c/8427347).

Add ScaleUVAddCols3 for exact 3x horizontal downscaling (dx == 0x30000
and boxheight <= 85) in ScaleUVBox, plus ScaleAddRow_AVX512BW and
ScaleAddRow_WASMSIMD dispatch, and port 3x/box scaling kernels in
scale_win.cc to 32/64-bit C++ intrinsics matching scale_gcc.cc:
- ScaleUVAddCols3_C (portable C)
- ScaleUVAddCols3_AVX2 and ScaleUVAddCols3_Any_AVX2 (scale_gcc.cc and
  scale_win.cc)
- ScaleUVAddCols3_AVX512VBMI (scale_gcc.cc and scale_win.cc)
- ScaleAddRow_SSE2, ScaleAddRow_AVX2, ScaleAddRow_AVX512BW,
  ScaleAddCols1_AVX512BW, ScaleAddCols2_AVX512BW, ScaleRowDown38_SSSE3,
  ScaleRowDown38_2_Box_SSSE3, and ScaleRowDown38_3_Box_SSSE3 in
  scale_win.cc for 32/64-bit Visual C and LIBYUV_ENABLE_ROWWIN
- ScaleUVAddCols3_NEON (32-bit ARM and 64-bit AArch64) and
  ScaleUVAddCols3_Any_NEON
- ScaleUVAddCols3_SME (ARMv9 Streaming SVE with whilelt predicate tail)
- ScaleUVAddCols3_RVV (RISC-V Vector vlseg3e32.v inline asm)
- ScaleUVAddCols3_LSX and ScaleUVAddCols3_Any_LSX (LoongArch LSX)
- ScaleAddRow_WASMSIMD, ScaleAddRow_Any_WASMSIMD,
  ScaleUVAddCols3_WASMSIMD, and ScaleUVAddCols3_Any_WASMSIMD
- ScaleUVAddCols3_HVX (Hexagon HVX vrdelta + vmpy_VuhRuh)
