Add wrap suggestions for record variants
This PR adds a suggestions to wrap an expression in a record struct/variant when encountering mismatched types, similarly to a suggestion to wrap expression in a tuple struct that was added before.
An example:
```rust
struct B {
f: u8,
}
enum E {
A(u32),
B { f: u8 },
}
fn main() {
let _: B = 1;
let _: E = 1;
}
```
```text
error[E0308]: mismatched types
--> ./t.rs:11:16
|
11 | let _: B = 1;
| - ^ expected struct `B`, found integer
| |
| expected due to this
|
help: try wrapping the expression in `B`
|
11 | let _: B = B { f: 1 };
