Description
Example:
#[derive(serde::Deserialize)]
struct Foo {}
When the cursor is on Deserialize and I open the assist menu, I would expect a "Replace qualified path with use option" that updates the code to
use serde::Deserialize;
#[derive(Deserialize)]
struct Foo {}
and updates any other uses of serde::Deserialize (both the derive macro & trait) in the same file to just Deserialize.

Research direction
Reproduce the example in rust-analyzer and trace the assist-menu handling for qualified paths, focusing on derive macro and trait paths. Done means the assist is offered for serde::Deserialize, inserts the use declaration, shortens the derive, and updates other matching uses in the same file.
