Adapting the lint list to Clippy's new metadata format
This is close to the end of a long living project to rewrite the lint metadata collection for Clippy. Progress on this has been tracked in #7172. This PR adds one of the last missing puzzle pieces, the actual display of all the changes that have been done in the background. A preview can be seen here: [Clippy's lint list](https://xfrednet.github.io/rust-clippy/master/index.html)
The styling has been discussed on [zulip](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Styling.20feedback.20for.20Clippy's.20lint.20list/near/239601067) but is still open to suggestion.
Side note: It has been fun working on the website where we don't have unit tests and everything is just tested by playing around. However, it's good that this chaos is contained into this one part of Clippy. 🐛

This updates all the deploy scripts and the deploy workflow.
The deploy workflow now runs the metadata collector to collect the lint
documentation. It also changes the files that are checked out in the
deploy workflow from master and adds an explanation why we have to do
this.
Explain flags missing in cargo check in --help
This commit closes#7389. As stated in the issue, `cargo clippy --help`
provides explanation for some flags and states that the rest are same
as in `cargo check --help`, even though some clippy specific flags
exist.
This commit extends the `cargo clippy --help` with two additional flags,
- `cargo clippy --fix`
- `cargo clippy --no-deps`
If there are more flags which are not present in `cargo check --help`
please bring these to my attention, I will include these aswell.
For now, I noticed only the two flags mentioned above.
changelog: `cargo clippy --help` now explains additional flags missing in `cargo check --help`.
Fix docs of disallowed_type
Add ability to name primitive types without import path
Move primitive resolution to clippy_utils path_to_res fn
Refactor Res matching, fix naming and docs from review
Use tcx.def_path_str when emitting the lint
As proposed in the pull request thread, there is some inconsistency in
handling the `--no-deps` flag which requires `--` before it, and
`--fix` flag which does not.
In this commit the `--no-deps` flag does not need the `--` anymore.
However, it can still be used that way: `cargo clipyy -- --no-deps`.
Use diagnostic items where possible
Clippy still uses a bunch of paths in places that could easily use already defined diagnostic items. This PR updates all references to such paths and also removes a bunch of them that are no longer needed after this cleanup.
Some paths are also used to construct new paths and can therefore not be removed that easily. I've added a doc comment to those instances that recommends the use of the diagnostic item where possible.
And that's it, cleaning crew signing off 🧹🗑️

`--no-deps` filled in with a little more information. Explain that
`--fix` implies `--no-deps`.
Explain that `--no-deps` is used with `cargo clippy --`, including
one example.
Prefer a code snipped over formatting the self type (`new_without_default`)

Store all HIR owners in the same container
This replaces the previous storage in a BTreeMap for each of Item/ImplItem/TraitItem/ForeignItem.
This should allow for a more compact storage.

Documented constant expression evaluation for `repeat_once`
