  -----------
  [RISCV] Remove codegen for vp_bitreverse, vp_bswap (#191643)

Part of the work to remove trivial VP intrinsics from the RISC-V
backend, see
https://discourse.llvm.org/t/rfc-remove-codegen-support-for-trivial-vp-intrinsics-in-the-risc-v-backend/87999

This splits off 2 intrinsics from #179622.
