Improve the usage message for `-Z dump-mir`.
Ouput now looks like this:
```
$ rustc -Z help
...
-Z arg-align-attributes -- emit align metadata for reference arguments
-Z dump-mir=val -- dump MIR state to file.
`val` is used to select which passes and functions to dump. For example:
`all` matches all passes and functions,
`foo` matches all passes for functions whose name contains 'foo',
`foo & ConstProp` only the 'ConstProp' pass for function names containing 'foo',
`foo | bar` all passes for function names containing 'foo' or 'bar'.
-Z dump-mir-dir=val -- the directory the MIR is dumped into
...
```
Fixes rust-lang#56558
