Declarative Macros 2.0 places macros at root, not at module level (nightly)

[samsieber]

I'm assuming that with #35896 (modularization), this is something we'll want to change.

For example, I try

#![feature(decl_macro)]

pub mod module {
  pub macro test_macro() {
    println!("hello world");
  }
}

And the macro ends up at the root of the documentation, even though with the 2018 edition I access it through "use whatever_crate_its_in::module::test_macro".

Closing as duplicate of #74355 - even though this issue is older, that one has more discussion.
