  [MLIR][NVVM] Add `ptxas-cmd-options` to pass flags to the downstream compiler (#127457)

This PR adds `cmd-options` to the `gpu-lower-to-nvvm-pipeline` pipeline
and the `nvvm-attach-target` pass, allowing users to pass flags to the
downstream compiler, *ptxas*.

Example:
```
mlir-opt -gpu-lower-to-nvvm-pipeline="cubin-chip=sm_80 ptxas-cmd-options='-v --register-usage-level=8'"
```
