  [mlir][Pass] Report error when passing options to pipelines via shorthand syntax (#185738)

When passing options to a pass pipeline that doesn't accept options,
mlir-opt exits with error code 1, but prints no error message when using
shorthand CLI syntax:

```
# Silent failure (no error message):
$ mlir-opt --tosa-to-linalg-pipeline=foo /dev/null
$ echo $?
1

# Same pipeline via --pass-pipeline syntax reports error:
$ mlir-opt --pass-pipeline='builtin.module(tosa-to-linalg-pipeline{foo})' /dev/null
<unknown>:0: error: failed to add `tosa-to-linalg-pipeline` with options `foo`
```

This PR adds replaces the silent call to `failure` with `errorHandler`
in `PassPipelineCLParser::addToPipeline`, matching the existing pattern
in `TextualPipeline::addToPipeline`.
