Feature request: destructure parameter code action/refactor

[adsick]

so basically if you have

struct Vector {
    x: f32,
    y: f32,
    z: f32,
}

fn length(vector: Vector) -> f32 {
    let Vector { x, y, z } = vector;
    (x * x + y * y + z * z).sqrt()
}

the line

let Vector { x, y, z } = vector;

could be auto-generated by performing a code action on vector parameter, I think it would be handy for many devs out there so maybe add this functionality to RA?

upd: it also could be "destructure parameter inplace"... whoa, RA is already capable of it, cool!
I mean this:

fn length(Vector { x, y, z }: Vector) -> f32 {
    (x * x + y * y + z * z).sqrt()
}

Duplicate of #8673 -- note that this already works for tuples, e.g. if you have fn length(v: (f32, f32, f32)).
