  [RISCV] Add Zvzip intrinsics (#186342)

In the RVV Clang builtins generator, a new prototype descriptor
`d` was added to represent vectors with `2 x LMUL`.

The `.ll` tests were generated by LLM and I have reviewed them.

And the .c tests were generated by
https://github.com/riscv-non-isa/riscv-rvv-intrinsic-doc/pull/431.
