Enable I422To{ARGB,RGBA,RGB24}Row_RVV
Run on SiFive internal FPGA:
I422ToARGB_Opt (~10x vs scalar)
I422ToRGBA_Opt (~10x vs scalar)
I420ToRGB24_Opt (~8x vs scalar)
LIBYUV_WIDTH=1280 LIBYUV_HEIGHT=720 LIBYUV_REPEAT=10
This CL manually sets rounding mode,
since we use fixed-point vector narrowing clip.
There is no definition about default value for fixed-point rounding mode.
https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc#38-vector-fixed-point-rounding-mode-register-vxrm
The behavior could be different on differet paltforms. To avoid unexpected behavior, we set rounding mode manually.
