Account for unbounded type param receiver in suggestions

When encountering

```rust
fn f<T>(a: T, b: T) -> std::cmp::Ordering {
    a.cmp(&b) //~ ERROR E0599
}
```

output

```
error[E0599]: no method named `cmp` found for type parameter `T` in the current scope
  --> $DIR/method-on-unbounded-type-param.rs:2:7
   |
LL | fn f<T>(a: T, b: T) -> std::cmp::Ordering {
   |      - method `cmp` not found for this type parameter
LL |     a.cmp(&b)
   |       ^^^ method cannot be called on `T` due to unsatisfied trait bounds
   |
   = help: items from traits can only be used if the type parameter is bounded by the trait
help: the following traits define an item `cmp`, perhaps you need to restrict type parameter `T` with one of them:
   |
LL | fn f<T: Ord>(a: T, b: T) -> std::cmp::Ordering {
   |       +++++
LL | fn f<T: Iterator>(a: T, b: T) -> std::cmp::Ordering {
   |       ++++++++++
```

Fix #120186.
