Add has_lib and bin_names fields to the versions API

[Turbo87]

https://docs.rs/cargo-manifest/latest/cargo_manifest/struct.Manifest.html#method.complete_from_abstract_filesystem is used to find implicit libraries or binaries in the crate file.

Tasks:

• find libraries, binaries, etc. in the crate file
• save that data in the database
• expose that data in the API
• adjust the install instructions on the web frontend depending on the data (see Show cargo install for crates with binaries #8883)
• figure out a way to backfill the data for existing versions

Related:

• Display cargo install crate-name rather than cargo add crate-name for binary crates #5882
• Show cargo install for crates with binaries #8883

This PR is ready for review now. The frontend part of this work will be opened in an independent PR, same for the backfilling code.

With the obvious caveat that we're now dependent on cargo-manifest's target discovery working the same way as cargo, this LGTM. (On the bright side, this is something that's easily re-backfilled later if there are any issues, and certainly not on any critical path for publishing or using crates.)

yeah, that's why I'm currently working on fixing some of the finer details of the target auto-discovery in cargo-manifest :D

#8951 has been merged, so this is now unblocked :)
