Merge #5846

5846: Add references to fn args during completion r=matklad a=adamrk

When completing a function call, if there is an argument taken as a ref or mut ref which matches the name and type of a variable in scope, we will insert a `&` or `&mut` when filling in the function arguments. This addresses https://github.com/rust-analyzer/rust-analyzer/issues/5449.

E.g. 
```rust
fn foo(x: &i32) {}
fn main() {
  let x = 5;
  foo # completing foo here generates `foo(&x)` now instead of `foo(x)`
}
```
