RISC-V: Add support for vector crypto extensions

This series adds basic support for the vector crypto extensions:
  * Zvbb
  * Zvbc
  * Zvkg
  * Zvkned
  * Zvkhn[a,b]
  * Zvksed
  * Zvksh
  * Zvkn
  * Zvknc
  * Zvkng
  * Zvks
  * Zvksc
  * Zvksg
  * Zvkt

This patch is based on the v20230620 version of the Vector Cryptography
specification. The specification is frozen and can be found here:
  https://github.com/riscv/riscv-crypto/releases/tag/v20230620

Binutils support is merged as 9fdc1b157b6e72f7dd98851a240c5fdb386a558e.
All extensions come with (passing) tests for the feature test macros.
