refacto use from_def_id_and_attrs_and_parts instead of an old trick
most of josha suggestions + check if def_id is not fake before using it in a query
Removed usage of Attributes in FnDecl and ExternalCrate. Relocate part of the Attributes fields as functions in AttributesExt.
rustdoc: Don't generate blanket impls when running --show-coverage
`get_blanket_impls` is the slowest part of rustdoc, and the coverage pass
completely ignores blanket impls. This stops running it at all, and also
removes some unnecessary checks in `calculate_doc_coverage` that ignored
the impl anyway.
We don't currently measure --show-coverage in perf.rlo, but I tested
this locally on cargo and it brought the time down from 2.9 to 1.6
seconds.
This also adds back a commented-out test; Rustdoc has been able to deal with `impl trait` for almost a year now.

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.
rustdoc: Use DiagnosticInfo in more parts of intra-doc links
This makes the code a lot less verbose.
This is separated into lots of tiny commits because it was easier for me that way, but the overall diff isn't that big if you want to read it at once.

rustdoc: Cleanup handling of associated items for intra-doc links
Helps with https://github.com/rust-lang/rust/issues/83761 (right now the uses of the resolver are all intermingled with uses of the tyctxt). Best reviewed one commit at a time.
r? ```@bugadani``` maybe? Feel free to reassign :)
Previously, the types looked like this:
- None means this is not an associated item (but may be a variant field)
- Some(Err) means this is known to be an error. I think the only way that can happen is if it resolved and but you had your own anchor.
- Some(Ok(_, None)) was impossible.
Now, this returns a nested Option and does the error handling and
fiddling with the side channel in the caller. As a side-effect, it also
removes duplicate error handling.
This has one small change in behavior, which is that
`resolve_primitive_associated_item` now goes through `variant_field` if
it fails to resolve something. This is not ideal, but since it will be
quickly rejected anyway, I think the performance hit is worth the
cleanup.
This also fixes a bug where struct fields would forget to set the side
channel, adds a test for the bug, and ignores `private_intra_doc_links`
in rustc_resolve (since it's always documented with
--document-private-items).
This prevents us from warning on links such as `<hello@example.com>`.
Note that we still warn on links such as `<hello@localhost>` because
they have no dots in them. However, the links will still work, even
though a warning is reported.
Instead, only load the crates that are linked to with intra-doc links.
This doesn't help very much with any of rustdoc's fundamental issues
with freezing the resolver, but it at least fixes a stable-to-stable
regression, and makes the crate loading model somewhat more consistent
with rustc's.
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.

Otherwise you get a lot of instances of `item.span.span()`, which is
just plain confusing. `item.span.inner()` conveys the correct meaning of
"get the type that `clean::Span` wraps".
Remove RefCell around `module_trait_cache`
This builds on https://github.com/rust-lang/rust/pull/82018 and should not be merged before.
## Don't require a `DocContext` for `report_diagnostic`
This is needed for the next commit, which needs mutable access to the `cx` from
within the `decorate` closure.
- Change `as_local_hir_id` to an associated function, since it only
needs a `TyCtxt`
- Change `source_span_for_markdown_range` to only take a `TyCtxt`
## Remove RefCell around module_trait_cache
This is mostly just changing lots of functions from `&DocContext` to `&mut DocContext`.
