[AArch64] Add SME implementation of I444ToARGBRow

This is based on an unrolled version of the existing SVE2 code. The
implementation in this case is a pure streaming-SVE (SSVE)
implementation based on the existing SVE2 implementation, we do not use
the ZA tile.

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.
