Misc refactorings
Various small re-orderings to check the HIR tree or AST before doing other checks. Also includes a small bug fix for `arc_with_small_send_sync` not actually checking for `Arc::new`.

Misc refactorings part 5
`toplevel_ref_arg` gets a small fix so it can be allowed on function arguments. Otherwise just some rearrangements.

add lint for recreation of an entire struct
This lint makes Clippy warn about situations where an owned struct is
essentially recreated by moving all its fields into a new instance of
the struct. The lint is not machine-applicable because the source
struct may have been partially moved.
This lint originated in something I spotted during peer review. While
working on their branch a colleague ended up with a commit where a
function returned a struct that 1:1 replicated one of its owned inputs
from its members. Initially I suspected they hadn’t run their code
through Clippy but AFAICS there is no lint for this situation yet.

### New lint checklist
- \[+] Followed [lint naming conventions][lint_naming]
- \[+] Added passing UI tests (including committed `.stderr` file)
- \[+] `cargo test` passes locally
- \[+] Executed `cargo dev update_lints`
- \[+] Added lint documentation
- \[+] Run `cargo dev fmt`

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 I mainly updated the versions, removed some very outdated crates, and added some new ones.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.

Lintcheck: Add URL to lint emission place in diff
This PR adds links to the emission code in our lintcheck CI. When reviewing changes, I would like to be able to see the bigger context, which isn't always included in the lint message. This PR adds a nice link to the lintcheck diff that allows for simple investigation of the code in question.
At first, I wanted to simply use the doc.rs links and call it a day, but then I figured out that some crates might have their source files remapped. Cargo was the crate that made me notice this. As a response, I made the link configurable. (See https://github.com/rust-lang/docs.rs/issues/2551 for a detailed explanation and possible solution to remove this workaround in the future.)
It's probably easiest to review the individual commits. The last one is just a dummy to showcase the change.

Create lint passes using `Conf`
This slightly reduces the amount of code changes needed to add a config to a lint and makes things makes things more consistent between passes. A dependence on the config being a static reference is also added. This would only ever be a problem if multiple crates end up compiled in a single process.
Other changes include:
* Removing useless `#[derive(..)]`s
* Removing `#[must_use]` on lint pass constructors.
* Unified the parsing of the `DisallowedPath` struct in lint passes.
* Update `disallowed_types` and `await_holding_invalid` messages to be consistent with other disallowed lints.
* Remove the `(from clippy.toml)` message. I plan on having all the configured lints point to point to a span in `clippy.toml` which will be more useful.
changelog: none
* Construct lint passes by taking `Conf` by reference.
* Use `HashSet` configs in less places
* Move some `check_crate` code into the pass constructor when possible.
