Lintcheck: Update crates and expand CI testset to 200 crates

This PR adds a new `ci_crates.toml` to lintcheck for our CI. The 200 crates take about 14 minutes, which is slightly more than the 10 I aimed for but still reasonable. The testset is constructed from:

* 5 crates that compile to binaries
* 4 crates that have been mentioned in ICE issues
* 1 crates "random" crates from `lintcheck_crates.toml`
* 190 crates from the top 200 crates from crates.io

During testing, I noticed a few panics in lintcheck. I've fixed them where possible, or at least improved the error message.

The new test set generates 500+ MB of json lints, which are compressed to a ~24mb artifact.

---

This PR also updates our `lintcheck_crates.toml`. I mainly updated the versions, removed some very outdated crates, and added some new ones. I targeted 25 crates as those are pretty fast to lint and a good precursor for our CI.

---

Optional TODO:

* It's likely that some crates are compiled several times. We could potentially safe some time, by using `--recursive` in our CI.
    This is something I want to investigate, but it shouldn't be a blocker for this PR.
