Add new architecture support: RISC-V

When hardware becomes available.

Will RISC-V be supported in the near future? I already purchased the StarFive VisionFive 2 and awaiting for the support is released.

@samiux we would need RVV 1.0 capable hardware for that to happen and AFAIK, there is no such hardware publicly available yet.

Hello, Allwinner D1-H now supports rvv, is there any progress?

@Cryolitia We recently acquired an RVV 1.0 capable system, we are currently investigating how to best fund the effort as it is quite a bit different from other SIMD engines. Some refactoring will be required and we don't want to break the other architectures. Please be patient.
