   [RISC-V] Zvk update to 0.9.7, Zvknc/Zvksc

Update the RISC-V Zvk (vector cryptography) extension support from 0.5
to version 0.9.7 (2023-05-31), per
    <https://github.com/riscv/riscv-crypto/releases/download/v20230531/riscv-crypto-spec-vector.pdf>

Differences:
     - Zvbc is dropped from Zvkn and Zvks, and by extension
       from Zvkng and Zvksg;
     - new combo extensions Zvknc and Zvksc are introduced,
      adding Zvbc to Zvkn and Zvks;
     - the experimentatl extensions are tagged as "0.9",
       from the earlier "0.5".
