At first you might think "why not just click through to the aliased
type?", but if a type alias instantiates all of the generic parameters
of the aliased type, then it can show layout info even though the
aliased type cannot (because we can't compute the layout of a generic
type). So I think it's still useful to show layout info for type
aliases.
Fix source code line number display and make it clickable again
Fixes https://github.com/rust-lang/rust/issues/85119.
I used the same logic we're using for other codeblocks: putting the line number `<span>`s into the `example-wrap` directly and then add `display: inline-flex` on `example-wrap`.

Unify rustc and rustdoc parsing of `cfg()`
This extracts a new `parse_cfg` function that's used between both.
- Treat `#[doc(cfg(x), cfg(y))]` the same as `#[doc(cfg(x)]
#[doc(cfg(y))]`. Previously it would be completely ignored.
- Treat `#[doc(inline, cfg(x))]` the same as `#[doc(inline)]
#[doc(cfg(x))]`. Previously, the cfg would be ignored.
- Pass the cfg predicate through to rustc_expand to be validated
Technically this is a breaking change, but doc_cfg is still nightly so I don't think it matters.

Reset the docs' copy path button after 1 second
I like that this copy path button on the top next to the type/module's name changes to a check mark when you successfully clicked and copied the path but I find it really weird how the icon stays that check mark forever after the first time of clicking it. Imagine you leave that documentation tab open and come back after 2 hours and you still see that check mark in that box because you copied the path 2 hours ago. You will probably be confused and you might've forgotten what that button even does (even more so currently where this is a new feature, or when you simply don't use it often), so I really think at some point it should go back to the ⎘ icon which, at least to me, pretty clearly indicates copying, whereas the check mark (if it stays there for so long) could falsely look like a verification mark indicating "this module is verified" or something like that.
I believe after a longer period of time it's not logical to still tell the user "yes you've copied this successful".
In addition to this timeout, maybe it could be made so that you can't copy again until this cooldown of 1 second is over, but I'm not sure how useful or user-friendly that feature would be so maybe it's fine the way it is now.
Also the timeout is cleared every time you click again so if you constantly click it, it won't reset during that.
Use flex more consistently
Builds on #84376, related to #84354.
- Fully replaces `float: right` with `flex` on `.content .out-of-band`.
- Uses `flex` more consistently with existing usage (on `h3`, `h4`, etc.).
Tested on various widths to make sure the pages behave as before.
check item.is_fake() instead of self_id.is_some()
Remove empty branching in Attributes::from_ast
diverse small refacto after Josha review
cfg computation moved in merge_attrs
refacto use from_ast twice for coherence
take cfg out of Attributes and move it to Item
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: make expand/collapse all ephemeral
The `[+]` in the upper right of a rustdoc page expands or collapses all toggles on the page. That state is stored across page loads, but is used inconsistently. This change explicitly stops storing or using the state.
This also moves the code for toggling display of trait implementations so that it's near the other toggling code.
Fixes#84318
Calculate `span` info on-demand
- Add helper `attr_span` for common reused function
- Stop storing `Span`s on `Item` directly; calculate them on demand instead
- Special case modules, which have different spans depending on whether
you use inner or outer attributes
- Special case impls with fake IDs, which can have either dummy spans (for auto traits) or the DefId of the impl block (for blanket impls)
- Use a fake ID for primitives instead of the ID of the crate; this lets
`source()` know that it should use a dummy span instead of the span of
the crate.
This shrinks `Item` from 48 to 40 bytes.

Revert "rustdoc: Hide `#text` in doc-tests"
See discussion in #84502 - I'm worried that #84445 may cause a lot of breakages if this were to hit stable, so I think it's safer to revert and work on the known correct fix#84478.
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.
