rustdoc: Remove unnecessary `is_crate` field from doctree::Module and clean::Module
It can be calculated on-demand even without a TyCtxt.
This also changed `json::conversions::from_item_kind` to take a whole item, which avoids
having to add more and more parameters.
Helps with https://github.com/rust-lang/rust/issues/76382.

Items are first built after rustdoc creates the TyCtxt. To allow
resolving the links before the TyCtxt is built, the links can't be
stored on `clean::Item` directly.
Remove unnecessary `Option` wrapping around `Crate.module`
I'm wondering if it was originally there so that we could `take` the
module which enables `after_krate` to take an `&Crate`. However, the two
impls of `after_krate` only use `Crate.name`, so we can pass just the
name instead.

rustdoc: Cleanup `html::render::Context`
- Move most shared fields to `SharedContext` (except for `cache`, which
isn't mutated anyway)
- Replace a use of `Arc` with `Rc`
- Make a bunch of fields private
- Add static size assertion for `Context`
- Don't share `id_map` and `deref_id_map`
There was no need to clone `id_map` because it was reset before each
item was rendered. `deref_id_map` was not reset, but it was keyed by
`DefId` and thus was unlikely to have collisions (at least for now).
Now we just clone the fields that need to be cloned, and instead create
fresh versions of the others.
Previously, `JsonRenderer::after_krate` called `krate.version.clone()`.
The problem was it did that after the version was already moved into the
cache, so it would always be None. The fix was to get the version from
the cache instead.
The same information is available everywhere; the only reason the dummy
cache was needed is because it waas previously stored in three different
places. This consolidates the info a bit so the cache in `DocContext` is
used throughout. As a bonus, it means `renderinfo` is used much much
less.
- Return a `Cache` from `run_global_ctxt`, not `RenderInfo`
- Remove the unused `render_info` from `run_renderer`
- Remove RefCell around `inlined`
- Add intra-doc links
Make `Clean` take &mut DocContext
- Take `FnMut` in `rustc_trait_selection::find_auto_trait_generics`
- Take `&mut DocContext` in most of `clean`
- Collect the iterator in auto_trait_impls instead of iterating lazily; the lifetimes were really bad.
This combined with https://github.com/rust-lang/rust/pull/82018 should hopefully help with https://github.com/rust-lang/rust/pull/82014 by allowing `cx.cache.exported_traits` to be modified in `register_res`. Previously it had to use interior mutability, which required either adding a RefCell to `cache.exported_traits` on *top* of the existing `RefCell<Cache>` or mixing reads and writes between `cx.exported_traits` and `cx.cache.exported_traits`. I don't currently have that working but I expect it to be reasonably easy to add after this.

- Changes `fn sess` to properly return a borrow with the lifetime of `'tcx`, not the mutable borrow.
[rustdoc-json] Make `header` a vec of modifiers, and FunctionPointer consistent
Bumps version number and adds tests, this is a breaking change. I can split this into two (`is_unsafe` -> `header` and `header: Vec<Modifiers>`) if desired.
Rationale: Modifiers are individual notes on a function, it makes more sense for them to be a list of an independent enum over a String which is inconsistently exposing the HIR representation (prefix_str vs custom literals).
Function pointers currently only support `unsafe`, but there has been talk on and off about allowing them to also support `const`, and this makes handling their modifiers consistent with handling those of a function, allowing better shared code.

clean up clean::Static struct
Having a `String` for the expression didn't make much sense, and even less when it's actually not used (except in json so I kept it).

Add abi field to `Method`
Also bumps version and adds a test (Will conflict with #81500, whichever is merged first)
Rationale: It's possible for methods to have an ABI. This should be exposed in the JSON.
Remove struct_type from union output
Also bumps the format number and adds a test
Rationale: It's illegal to have unions of the form `union Union(i32, f32);`, or `union Union;`. The struct_type field was recently removed from the rustdoc Union AST, at which time this field was changed to always just read "union". It makes sense to completely remove it, as it provides no information.
