:wave: Hey,

This PR enables fuzzing SIMD instructions for the RISC-V backend. This is the only backend that requires a extension (has_v) for SIMD to work, so we need to check that it has been enabled before allowing SIMD types and instructions.

I've ran this for a while with icache and It's no longer crashing. But I haven't been able to run fuzzgen very well since I don't have a machine with the V extension, and running it with QEMU is quite slow.
