Simplify trim-paths feature by merging all debuginfo options together

This PR simplifies the trim-paths feature by merging all debuginfo options together, as described in https://github.com/rust-lang/rust/issues/111540#issuecomment-1994010274.

And also do some correctness fixes found during the review.
