Description
Exported macros that invokes other macros in the same crate without $crate:: prefix should be linted, as that requires users doing use the_crate::{the_macro, the_other_macro} (or #[macro_use] extern) even if the only thing they want to use is the_macro.

Research direction
Start with the linked Rust 2018 macro changes documentation to understand the required $crate:: behavior. Then locate rust-clippy's lint implementation and test entry points for exported macros. Done means exported macros that invoke same-crate macros without the prefix are detected and the stated import scenarios no longer require users to import the invoked macro separately.
