Rollup merge of #84029 - drahnr:master, r=petrochenkov
add `track_path::path` fn for usage in `proc_macro`s Adds a way to declare a dependency on external files without including them, to either re-trigger the build of a file as well as covering the use case of including dependencies within the `rustc` invocation, such that tools like `sccache`/`cachepot` are able to handle references to external files which are not included. Ref #73921
