[AArch64] Add SVE2 implementation of RGB24ToARGBRow

This can make use of the existing helper functions for RAWToARGBRow_SVE2
and RAWToRGBARow_SVE2 since the layouts are similar, we just need to
adjust the TBL constants to match the different input layout.

Observed reduction in runtime compared to the existing Neon kernel:

Cortex-A510: -25.6%
Cortex-A720: -15.2%
  Cortex-X2: -10.2%
  Cortex-X4: -30.2%

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 on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
