- Add `parent_module` to `DocFragment`
- Require the `parent_module` of the item being inlined
- Preserve the hir_id for ExternCrates so rustdoc can find the parent module later
- Take an optional `parent_module` for `build_impl` and `merge_attrs`.
Preserve the difference between parent modules for each doc-comment.
- Support arbitrarily many re-exports in from_ast. In retrospect this is
probably not used and could be simplified to a single
`Option<(Attrs, DefId)>`.
- Don't require the parent_module for all `impl`s, just inlined items
In particular, this will be `None` whenever the attribute is not on a
re-export.
- Only store the parent_module, not the HirId
When re-exporting a re-export, the HirId is not available. Fortunately,
`collect_intra_doc_links` doesn't actually need all the info from a
HirId, just the parent module.

Only get ImplKind::Impl once
With this, the code panics in one place instead of two.

#58972 ignored extern_traits because before #65983 was fixed, they
would always fail to resolve, giving spurious warnings.
This undoes that change, so extern traits are now seen by the
`collect_intra_doc_links` pass. There are also some minor changes in
librustdoc/fold.rs to avoid borrowing the extern_traits RefCell more
than once at a time.

Previously unstable impls were skipped, which meant that any impl with an
unstable method would get skipped.

Reintroduce spotlight / "important traits" feature
(Reopened version of https://github.com/rust-lang/rust/pull/74111 because Github is broken, see discussion there)
Fixes https://github.com/rust-lang/rust/issues/73785
This PR reintroduces the "spotlight" ("important traits") feature.
A couple changes have been made:
As there were concerns about its visibility, it has been moved to be next to the return type, as opposed to being on the side.
It also no longer produces a modal, it shows the traits on hover, and it can be clicked on to pin the hover bubble.
It also works fine on mobile:

This reverts commit 1244ced9580b942926afc06815e0691cf3f4a846.

Currently dependency crates of the standard library can sometimes leak
into error messages such as when traits to import are suggested.
Additionally they can leak into documentation such as in the list of
"all traits implemented by `u32`". The dependencies of the standard
library, however, are intended to be private.
The dependencies of the standard library can't actually be stabl-y
imported nor is the documentation that relevant since you can't import
them on stable either. This commit updates both the compiler and rustdoc
to ignore unstable traits in these two scenarios.
Specifically the suggestion for traits to import ignore unstable traits,
and similarly the list of traits implemented by a type excludes unstable
traits.
This commit is extracted from #73441 where the addition of some new
dependencies to the standard library was showed to leak into various
error messages and documentation. The intention here is to go ahead and
land these changes ahead of that since it will likely take some time to
land.

fix more clippy findings
* reduce references on match patterns (clippy::match_ref_pats)
* Use writeln!(fmt, "word") instead of write!(fmt, "word\n") (clippy::write_with_newline)
* libtest: remove redundant argument to writeln!() (clippy::writeln_empty_string)
* remove unneeded mutable references (cippy::unnecessary_mut_passed)
* libtest: declare variables as floats instead of casting them (clippy::unnecessary_cast)
* rustdoc: remove redundant static lifetimes (clippy::redundant_static_lifetimes)
* call .as_deref() instead of .as_ref().map(Deref::deref) (clippy::option_as_ref_deref)
* iterate over a maps values directly. (clippy::for_kv_map)
* rustdoc: simplify boolean condition (clippy::nonminimal_bool)
* Use ?-operator in more places (clippy::question_mark, had some false negatives fixed recently)
* rustdoc: Use .any(p) instead of find(p).is_some(). (clippy::search_is_some)
* rustdoc: don't call into_iter() on iterator. (clippy::identity_conversion)

Remove spotlight
I had a few comments saying that this feature was at best misunderstood or not even used so I decided to organize a poll about on [twitter](https://twitter.com/imperioworld_/status/1232769353503956994). After 87 votes, the result is very clear: it's not useful. Considering the amount of code we have just to run it, I think it's definitely worth it to remove it.

* Generate links to the primitive type docs for re-exports.
* Don't ICE on cross crate primitive type re-exports.
* Make primitive type re-exports show up cross crate.

Use named fields for `{ast,hir}::ItemKind::Impl`
Currently, the widely used `ItemKind::Impl` variant is a tuple with seven fields. I want to add an eighth in #68140, which means I have to update most matches on this variant anyways. Giving a name to each field improves readability and makes future changes of this nature much simpler.
This change will cause several tools to break. I will fix them once this is merged.

The only two uses of the associated methods are in librustc_mir and
librustdoc. Please tell me if there is a better choice.
