Add cargo collect-metadata as an cargo alias for the metadata collection lint

[xFrednet]

This PR adds a new alias to run the metadata collection monster on clippy_lints. I'm currently using it to create the metadata_collection.json file and I plan to use it in the deply.sh script. Having it as a new alias enables us to simply use:

cargo collect-metadata

It sometimes requires running cargo clean before collecting the metadata due to caching. I'm still debating if I should include a cargo clean as part of the run_metadata_collection_lint test or not. Input on this would be greatly appreciated 🙃

That's it, just a small change that can be reviewed and merged in parallel to #7214.

All good. Such PRs to the same topic are always better to be reviewed by one person. Otherwise someone else has to get up to speed first, which would take a long time with this monster :D

I'll review this and the other PR this weekend (no excuses this time).

Sounds good and I'm happy that the name monster is slowly getting accepted ^^.

The first implementation was a big chunk of code. These PRs that are based on the monster are lucky pretty small. You can take your time with the reviews as they are not holding me back 🙃

@bors r+

Thanks! This should not interfere with the review/merge of #7214, so I merging it before that, so I can easier test #7214 locally myself.
