Auto merge of #74653 - petrochenkov:pmenv, r=dtolnay
proc_macro: Add API for tracked access to environment variables Continuation of https://github.com/rust-lang/rust/pull/71858. `proc_macro::tracked_env::var` is similar to regular `env::var` called from a proc macro, except that it also adds the accessed variable to depinfo.
