Rollup merge of #125987 - estebank:issue-122622, r=Nadrieril

When `derive`ing, account for HRTB on `BareFn` fields

When given

```rust
trait SomeTrait {
    type SomeType<'a>;
}

#[derive(Clone)]
struct Foo<T: SomeTrait> {
    x: for<'a> fn(T::SomeType<'a>)
}
```

expand to

```rust
impl<T: ::core::clone::Clone + SomeTrait> ::core::clone::Clone for Foo<T>
    where for<'a> T::SomeType<'a>: ::core::clone::Clone {
    #[inline]
    fn clone(&self) -> Foo<T> {
        Foo { x: ::core::clone::Clone::clone(&self.x) }
    }
}
```

instead of the previous invalid

```
impl<T: ::core::clone::Clone + SomeTrait> ::core::clone::Clone for Foo<T>
    where T::SomeType<'a>: ::core::clone::Clone {
    #[inline]
    fn clone(&self) -> Foo<T> {
        Foo { x: ::core::clone::Clone::clone(&self.x) }
    }
}
```

Fix #122622.
