Add RGBToNV21Matrix function
- implement wrappers with RAW, RGB24, NV21 and JNV21 to call it.

Zen5
Was [       OK ] LibYUVConvertTest.RAWToJNV21_Opt (1146 ms)
Now [       OK ] LibYUVConvertTest.RAWToJNV21_Opt (1446 ms)
reason - the new code uses 1 pass for RAWToY but 2 pass for RAWToARGB,ARGBToUV.  needs 1 RGBToUV

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.
