feat: Sort items by trait definition assist This PR replaces the "Sort **methods** by trait definition" assist with a "Sort **items** by trait definition" assist that sorts all items, not just methods. ![sort-items-by-trait-def-showcase](https://user-images.githubusercontent.com/38225716/166491828-0bc10dbd-91be-408f-9fe0-636ef5e99377.gif)
