`include!` macro silently gives empty string if destination file is outside of the crate

code snippet to reproduce: (Please refer to the repo to see the exact file tree)

include!("in-src.rs");
include!("../in-crate.rs");
include!("../../in-workspace.rs");

fn main() {
    in_src();
    in_crate();
    in_workspace();
}

The issue is threefold:

1. The function name of in_workspace does not autocomplete in main()
2. Hovering over in_workspace(); shows nothing
3. Clicking "Inline macro" feature from light bulb menu for include!("../../in-workspace.rs") just deletes the line

The build result works as expected, so this should be rust-analyzer specific.

Begin with the linked minimal reproduction and trace include!(...) handling for in-src.rs, ../in-crate.rs, and ../../in-workspace.rs. Compare autocomplete, hover, and Inline macro behavior; done means the workspace-outside destination is analyzed consistently without deleting the macro line.
