  -----------
  [RISCV][RFC] add inst support of zbkb

This commit add instructions supports of `zbkb` which defined in scalar cryptography extension version v1.0.0 (has been ratified already).

Most of the zbkb directives reuse parts of the zbp and zbb directives, so this patch just modified some of the inst aliases and predicates.
