Developing for RISC-V Vector extension (RVV)

Since RVV is not widely available, we still can check validity of implementation using either QEMU or Spike emulator.

To use Spike one has to specify the toolchain:

$ cmake -B rvvbuild -DCMAKE_TOOLCHAIN_FILE=toolchain-rvv-spike.cmake
$ cmake --build rvvbuild
$ cd rvvbuild

To use QEMU, please refer to .github/workflows/rvv-128-clang-17.yml for command line options.
