Esteban Küber 5e6da720f6 Account for RPITIT in E0310 explicit lifetime constraint suggestion
When given

```rust
trait Original {
    fn f() -> impl Fn();
}

trait Erased {
    fn f(&self) -> Box<dyn Fn()>;
}

impl<T: Original> Erased for T {
    fn f(&self) -> Box<dyn Fn()> {
        Box::new(<T as Original>::f())
    }
}
```

avoid suggestion to restrict the `Trait::{opaque}` type in a `where` clause:

```
error[E0310]: the associated type `<T as Original>::{opaque#0}` may not live long enough
  --> $DIR/missing-static-bound-from-impl.rs:11:9
   |
LL |         Box::new(<T as Original>::f())
   |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |         |
   |         the associated type `<T as Original>::{opaque#0}` must be valid for the static lifetime...
   |         ...so that the type `impl Fn()` will meet its required lifetime bounds
```
