Make suggestions verbose.
When encountering `method(type)` bound, suggest `method(..)` instead of `method()`.

error: argument types not allowed with return type notation
--> $DIR/bad-inputs-and-output.rs:9:23

LL | fn foo<T: Trait<method(i32): Send>>() {}
| ^^^^^
|
help: remove the input types
|
LL - fn foo<T: Trait<method(i32): Send>>() {}
LL + fn foo<T: Trait<method(..): Send>>() {}

```
When encountering both return type and arg list that isn't `..`, suggest replacing both.

help: use the right argument notation and remove the return type
|
LL - fn bar<T: Trait<method() -> (): Send>>() {}
LL + fn bar<T: Trait<method(..): Send>>() {}

```
When encountering a return type, suggest removing it including the leading whitespace.
