Esteban Küber 11061831f7 Mention type that could be Clone but isn't in more cases
When encountering a moved value of a type that isn't `Clone` because of unmet obligations, but where all the unmet predicates reference crate-local types, mention them and suggest cloning, as we do in other cases already:

```
error[E0507]: cannot move out of `foo`, a captured variable in an `Fn` closure
  --> f111.rs:14:25
   |
13 | fn do_stuff(foo: Option<Foo>) {
   |             --- captured outer variable
14 |     require_fn_trait(|| async {
   |                      -- ^^^^^ `foo` is moved here
   |                      |
   |                      captured by this `Fn` closure
15 |         if foo.map_or(false, |f| f.foo()) {
   |            ---
   |            |
   |            variable moved due to use in coroutine
   |            move occurs because `foo` has type `Option<Foo>`, which does not implement the `Copy` trait
   |
note: if `Foo` implemented `Clone`, you could clone the value
  --> f111.rs:4:1
   |
4  | struct Foo;
   | ^^^^^^^^^^ consider implementing `Clone` for this type
...
15 |         if foo.map_or(false, |f| f.foo()) {
   |            --- you could clone this value
```

error[E0382]: borrow of moved value: `n`
