I still have to fix some tests, but I wanted early feedback if this is a desirable change. I may add a "pretty" option that allows other users (like the reproducer) to continue to use the single-line format |

This PR makes `dump-pass-pipeline` pretty-print the dumped pipeline. For
large pipelines the current behavior produces a wall of text that is
hard to visually navigate.
For the command
```bash
mlir-opt --pass-pipeline="builtin.module(flatten-memref, expand-strided-metadata,func.func(arith-expand,func.func(affine-scalrep)))" --dump-pass-pipeline
```
Before:
```bash
Pass Manager with 3 passes:
builtin.module(flatten-memref,expand-strided-metadata,func.func(arith-expand{include-bf16=false include-f8e8m0=false},func.func(affine-scalrep)))
```
After:
```bash
Pass Manager with 3 passes:
builtin.module(
flatten-memref,
expand-strided-metadata,
func.func(
arith-expand{include-bf16=false include-f8e8m0=false},
func.func(
affine-scalrep
)
)
)
```
Another nice feature of this is that the pretty-printed string can still
be copy/pasted into `-pass-pipeline` using a quote:
```bash
$ bin/mlir-opt --dump-pass-pipeline test.mlir --pass-pipeline='
builtin.module(
flatten-memref,
expand-strided-metadata,
func.func(
arith-expand{include-bf16=false include-f8e8m0=false},
func.func(
affine-scalrep
)
)
)'
```
