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
