  [RISCV] Combine 3 bit-manip extensions into `B` (#132858)

Like cryptography extensions like `Zk`, `B` (a combination of `Zba`,
`Zbb` and `Zbs` extensions) can be useful if we handle this extension as
a combination.
If all `Zba`, `Zbb` and `Zbs` extensions are enabled, it also enables
the `B` extension.
