[PATCH v5 02/15] target/riscv: Refactor vector-vector translation macro |

From: Kiran Ostrolenk <kiran.ostrolenk@codethink.co.uk>
Refactor the non SEW-specific stuff out of `GEN_OPIVV_TRANS` into
function `opivv_trans` (similar to `opivi_trans`). `opivv_trans` will be
used in proceeding vector-crypto commits.
