Charalampos Mitrodimas f20ee1f490 riscv: SM3: Provide a Zvksh-based implementation
The upcoming RISC-V vector crypto extensions feature
a Zvksh extension, that provides SM3-specific istructions.
This patch provides an implementation that utilizes this
extension if available.

Tested on QEMU and no regressions observed.
