YUV to RGB avoid avx assist

Here are the functions flagged for mixing both SSE and AVX (or AVX-512)
instructions, which can trigger an AVX transition/assist performance
penalty:

Libyuv Functions addressed in this CL
   * I422ToARGBRow_AVX512BW
   * HalfFloatRow_SSE2

Not addressed:
   * ScaleFilterCols_SSSE3

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.
