Esteban Küber adb5ecabdb Tweak invalid RTN errors
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.

```
error: return type not allowed with return type notation
  --> $DIR/bad-inputs-and-output.rs:12:25
   |
LL | fn bar<T: Trait<method() -> (): Send>>() {}
   |                         ^^^^^^
   |
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.

```
