Auto merge of #38024 - jseyfried:avoid_needless_proc_macro_deps, r=nrc
Avoid loading needless proc-macro dependencies

Fixes #37958 when no proc-macros are exported; in particular, without `pub extern crate proc_macros;`, `#![feature(macro_reexport)]`, or `#![feature(use_extern_macros)]`.

I opened https://github.com/rust-lang/cargo/issues/3334 for exported proc macros.
