  [clang][NVVM][NVPTX] Remove pzo modifier for rs rounding mode conversions (#225012)

This change removes the `pzo` modifier from the `fp16x2` conversion
intrinsics with `rs` rounding mode. This was added in
https://github.com/llvm/llvm-project/pull/214667 due to a bug in the
developer-preview version of the 13.4 PTX ISA docs, and this change
aligns it with the latest PTX ISA docs for 13.4.
