Auto merge of #90677 - bobrippling:suggest-tuple-parens, r=camelid

Suggest tuple-parentheses for enum variants

This follows on from #86493 / #86481, making the parentheses suggestion. To summarise, given the following code:

```rust
fn f() -> Option<(i32, i8)> {
    Some(1, 2)
}
```

The current output is:

```
error[E0061]: this enum variant takes 1 argument but 2 arguments were supplied
 --> b.rs:2:5
  |
2 |     Some(1, 2)
  |     ^^^^ -  - supplied 2 arguments
  |     |
  |     expected 1 argument

error: aborting due to previous error

For more information about this error, try `rustc --explain E0061`.
```

With this change, `rustc` will now suggest parentheses when:
- The callee is expecting a single tuple argument
- The number of arguments passed matches the element count in the above tuple
- The arguments' types match the tuple's fields
