Fix lints handling in rustdoc
Part of #60664: now lints are handled just like any other lints you would setup in rustc. Still remains to handle `missing code examples` and `missing_docs` as part of the same group.

A lot of these static symbols are pre-interned.
|
|
|
|
And also the equality between `Path` and strings, because `Path` is made
up of `Symbol`s.

rustdoc: remove def_ctor hack.
~~No longer necessary since we have `describe_def`.~~
Turns out `def_ctor` was used in conjunction with abusing `tcx.type_of(def_id)` working on both type definitions and `impl`s (specifically, of builtin types), but also reimplementing a lot of the logic that `Clean` already provides on `Ty` / `ty::TraitRef`.
The first commit now does the minimal refactor to keep it working, while the second commit contains the rest of the refactor I started (parts of which I'm not sure we need to keep).

Don't try to render auto-trait bounds with any inference variables
Previously, we checked if the target of a projection type was itself an
inference variable. However, for Rustdoc rendering purposes, there's no
distinction between an inference variable ('_') and a type containing
one (e.g. (MyStruct<u8, _>)) - we don't want to render either of them.
Fixes #60269
Due to the complexity of the original bug, which spans three different
crates (hyper, tower-hyper, and tower), I have been unable to create a
minimized reproduction for the issue.

[wg-async-await] Drop `async fn` arguments in async block
Fixes #54716.
This PR modifies the HIR lowering (and some other places to make this work) so that unused arguments to a async function are always dropped inside the async move block and not at the end of the function body.
```
async fn foo(<pattern>: <type>) {
async move {
}
} // <-- dropped as you "exit" the fn
// ...becomes...
fn foo(__arg0: <ty>) {
async move {
let <pattern>: <ty> = __arg0;
} // <-- dropped as you "exit" the async block
}
```
However, the exact ordering of drops is not the same as a regular function, [as visible in this playground example](https://play.rust-lang.org/?version=stable&mode=debug&edition=2015&gist=be39af1a58e5d430be1eb3c722cb1ec3) - I believe this to be an unrelated issue. There is a [Zulip topic](https://rust-lang.zulipchat.com/#narrow/stream/187312-t-compiler.2Fwg-async-await/topic/.2354716.20drop.20order) for this.

This commit displays the original pattern in generated documentation for
async functions rather than the synthesized pattern.

Fix invalid bounds string generation in rustdoc
Fixes #58737.
Very weird and I'm not sure this is the best fix around. However, trying to fix it beforehand seems overly complicated compared to the gain (in `clean`, it wouldn't change anything since we **have to** return something so that wouldn't work, and in `hir`, I'm afraid I'd break something else for very little gain).
Also, I wasn't able to make a small code to reproduce the issue. The only way to test is to document `crossbeam` directly and check the `Scope` struct...

RFC 2008: Enum Variants

This commit adds support for non-exhaustive enum variants in rustdoc,
extending the existing support for non-exhaustive enums and structs.

This commit makes two changes - separating the `NodeId` that identifies
an enum variant from the `NodeId` that identifies the variant's
constructor; and no longer creating a `NodeId` for `Struct`-style enum
variants and structs.
Separation of the variant id and variant constructor id will allow the
rest of RFC 2008 to be implemented by lowering the visibility of the
variant's constructor without lowering the visbility of the variant
itself.
No longer creating a `NodeId` for `Struct`-style enum variants and
structs mostly simplifies logic as previously this `NodeId` wasn't used.
There were various cases where the `NodeId` wouldn't be used unless
there was an unit or tuple struct or enum variant but not all uses of
this `NodeId` had that condition, by removing this `NodeId`, this must
be explicitly dealt with. This change mostly applied cleanly, but there
were one or two cases in name resolution and one case in type check
where the existing logic required a id for `Struct`-style enum variants
and structs.

Add const generics to rustdoc
Split out from #53645. This work is a collaborative effort with @yodaldevoid.
The `FIXME`s are waiting on a refactor to `LazyConst`. I'll address these in a follow up, but I thought it would be better to implement the rest now to avoid bitrot.
