Suggest replacing an inexisting field for an unmentioned field

Fix #87938

This PR adds a suggestion to replace an inexisting field for an
unmentioned field. Given the following code:
```rust
enum Foo {
    Bar { alpha: u8, bravo: u8, charlie: u8 },
}

fn foo(foo: Foo) {
    match foo {
        Foo::Bar {
            alpha,
            beta, // `bravo` miswritten as `beta` here.
            charlie,
        } => todo!(),
    }
}
```
the compiler now emits the error messages below.
```text
error[E0026]: variant `Foo::Bar` does not have a field named `beta`
 --> src/lib.rs:9:13
  |
9 |             beta, // `bravo` miswritten as `beta` here.
  |             ^^^^
  |             |
  |             variant `Foo::Bar` does not have this field
  |             help: `Foo::Bar` has a field named `bravo`: `bravo`
```

Note that this suggestion is available iff the number of inexisting
fields and unmentioned fields are both 1.
