Add include and exclude information to metadata

[GuillaumeGomez]

I'll need this information to fix rust-lang/rust-clippy#11677. I'll also send a PR to cargo_metadata once merged.

Of course, if there is another way to retrieve this information without needing this PR, I'd love to hear it. :)

While it might be useful to have include and exclude in cargo metadata output, it doesn't seem to be a proper way to fix rust-lang/rust-clippy#11677. The solution might end up reimplement the logic Cargo find and package files, which includes .gitignore, shell glob syntax, symlinks handling, git dirty status, and other details (see #11405). cargo package --list might be more reliable, but not 100% accurate (see #8407 and #11666).

I would suggest starting the discussion from an issue, and jump back to implementation when the design is settled.

[GuillaumeGomez]

Yes that's a good point. I'll open an issue so it can be discussed.

I opened #13331.

☔ The latest upstream changes (presumably #13703) made this pull request unmergeable. Please resolve the merge conflicts.

I'll close this in favor of high level discussions in #13331. When we have a settled design we can always come back and revisit this implementation. Thank you :)
