- Use -fno-tree-vectorize and -fno-tree-slp-vectorize instead of
Clang-only -fno-vectorize and -fno-slp-vectorize in CMakeLists.txt,
riscv-clang.cmake, BUILD.gn, and BUILD.bazel for GCC and Clang
compatibility.
- Split row_rvv.cc and scale_rvv.cc into a dedicated libyuv_rvv target
in BUILD.gn and define LIBYUV_RVV so callers in row.h and scale_row.h
can dispatch to RVV kernels when built without global -march=rv64gcv.
- Guard the x86 AVX512-BF16 vdpphps inline assembly probe in
util/cpuid.c with __i386__ / __x86_64__.
- Replace new/delete and new[]/delete[] with calloc/malloc/free in
source/mjpeg_decoder.cc and util/yuvconvert.cc to avoid C++ standard
library dependencies, and link libm for yuvconstants and
libyuv_unittest in CMakeLists.txt.
Test: cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ..

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

This CL aims to support custom compiler flags.
Because upstream clang has supported to build for x280 with -mcpu=sifive-x280.
