Add intention to expand S { .. } in patterns

[vlad20012]

In rust it's possible to skip some fields in patterns by adding ..:

struct S { a: i32, b: i32, c:i32 }
fn foo(s: S) {
    let S { a, .. } = s;
}

And for tuple struct case:

struct S(i32, i32, i32);
fn foo(s: S) {
    let S(a, ..) = s;
}

It would be nice to have an intention to replace such .. with the actual fields.

If no objection, I would like to work on this issue.

Maybe it's reasonable to implement analysis for E0027 & E0023 first
