Add Split/Merge RGB/ARGB/XRGB Row_RVV

* Run on SiFive internal FPGA:

SplitRGBPlane_Opt (~6.87x vs scalar)

SplitARGBPlane_Opt (~10.77x vs scalar)

SplitXRGBPlane_Opt (~18.69x vs scalar)

MergeRGBPlane_Opt (~3.63x vs scalar)

MergeARGBPlane_Opt (~3.50x vs scalar)

MergeXRGBPlane_Opt (~2.90x vs scalar)

LIBYUV_WIDTH=1280 LIBYUV_HEIGHT=720 LIBYUV_REPEAT=10

- include a fix to avoid implict conversion warning between size_t & int.

Bug: libyuv:956

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.
