macros: Future proof `#[no_link]` This PR future proofs `#[no_link]` for macro modularization (cc #35896). First, we resolve all `#[no_link] extern crate`s. `#[no_link]` crates without `#[macro_use]` or `#[macro_reexport]` are not resolved today, this is a [breaking-change]. For example, ```rust ``` Any breakage can be fixed by simply removing the `#[no_link] extern crate`. Second, `#[no_link] extern crate`s will define an empty module in type namespace to eventually allow importing the crate's macros with `use`. This is a [breaking-change], for example: ```rust mod syntax {} //< This becomes a duplicate error. ``` r? @nrc
