RISC-V: Update crypto vector ISA info with latest spec

  This patch add the Zvkb subset of crypto vector extension. The
corresponding test cases have aslo been modified.

gcc/ChangeLog:

        * common/config/riscv/riscv-common.cc: Add zvkb ISA info.
        * config/riscv/riscv.opt: Add Mask(ZVKB)

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/zvkn-1.c: Replace zvbb with zvkb.
        * gcc.target/riscv/zvkn.c:  Ditto.
        * gcc.target/riscv/zvknc-1.c: Ditto.
        * gcc.target/riscv/zvknc-2.c: Ditto.
