Support RVV v0.12 intrinsics for row_rvv.cc & scale_rvv.cc

1. Add two defined marco LIBYUV_RVV_HAS_TUPLE_TYPE & LIBYUV_RVV_HAS_VXRM_ARG

Intrinsic v0.12 introduces
- tuple type in segment load & store
- vxrm argument in fixed-point intrinsics (e.g vnclip)

These two marcos are controled by __riscv_v_intrinsic.

2. Support RVV v0.12 intrinsics in row_rvv.cc & scale_rvv.cc

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.
