`single_use_lifetimes`: Don't suggest deleting lifetimes with bounds

Closes #117965

```
9 |     pub fn get<'b: 'a>(&'b self) -> &'a str {
  |                ^^       -- ...is used only here
  |                |
  |                this lifetime...
```

In this example, I think the `&'b self` can be replaced with the bound itself, yielding `&'a self`, but this would require a deeper refactor. Happy to do as a follow-on PR if desired.
