rustdoc: avoid inlining items with duplicate `(type, name)`
Fixes #99221

Add macro support in jump to definition feature
Fixes #91174.
To do so, I check if the span comes from an expansion, and if so, I infer the original macro `DefId` or `Span` depending if it's a defined in the current crate or not.
There is one limitation due to macro expansion though:
```rust
macro_rules! yolo { () => {}}
fn foo() {
yolo!();
}
```
In `foo`, `yolo!` won't be linked because after expansion, it is replaced by nothing (which seems logical). So I can't get an item from the `Visitor` from which I could tell if its `Span` comes from an expansion.
I added a test for this specific limitation alongside others.
Demo: https://rustdoc.crud.net/imperio/macro-jump-to-def/src/foo/check-source-code-urls-to-def-std.rs.html
As for the empty macro issue that cannot create a jump to definition, you can see it [here](https://rustdoc.crud.net/imperio/macro-jump-to-def/src/foo/check-source-code-urls-to-def-std.rs.html#35).

rustdoc: optimize loading of source sidebar
The source sidebar has a setting to remember whether it should be open or
closed. Previously, this setting was handled in source-script.js, which
is loaded with `defer`, meaning it is often run after the document is rendered.
Since CSS renders the source sidebar as closed by default, changing this
after the initial render results in a relayout.
Instead, handle the setting in storage.js, which is the first script to load
and is the only script that blocks render. This avoids a relayout and means
navigating between files with the sidebar open is faster.

Create elided lifetime parameters for function-like types
Split from https://github.com/rust-lang/rust/pull/97720
This PR refactor lifetime generic parameters in bare function types and parenthesized traits to introduce the additional required lifetimes as fresh parameters in a `for<>` bound.
This PR does the same to lifetimes appearing in closure signatures, and as-if introducing `for<>` bounds on closures (without the associated change in semantics).

Improve loading of crates.js and sidebar-items.js
Now that the "All Crates" dropdown is only rendered on the search results page,
there is no need to load crates.js on most pages. Load it only on crate pages.
Also, add the `defer` attribute so it does not block HTML parsing.
For sidebar-items.js, move the script tag to `<head>`. Since it already has the
defer attribute it won't block loading. The defer attribute does preserve
ordering between scripts, so instead of the callback on load, it can set a
global variable on load, which is slightly simpler. Also, since it is required
to finish rendering the page, beginning its load earlier is better.
Remove generation and handling of sidebar-vars. Everything there can be computed
with information available in JS via other means.
Remove the extra_scripts fields of the `Page` template. They were only
used by source-script.js and source-files.js, which are now linked by the template
based on whether it is rendering a source page.
Remove the "other" wrapper in the sidebar. It was unnecessary.

Make debug_triple depend on target json file content rather than file path
This ensures that changes to target json files will force a recompilation. And more importantly that moving the files doesn't force a recompilation.
This should fix https://github.com/Rust-for-Linux/linux/issues/792 (cc ``@ojeda)``

rustdoc: remove tuple link on round braces
This is #98069 but for tuples. The reasoning is the same:
* This PR also changes it so that tuples with all-generic elements still link to the primitive.tuple.html page, just like slices. So there still plenty of on-ramps for anybody who doesn't know about it.
* It's too hard to see when round braces are a separate link from the type inside of them.
* It's too hard to click even if you do notice them.
Before:
* impl [ToSocketAddrs](https://doc.rust-lang.org/nightly/std/net/trait.ToSocketAddrs.html) for [(](https://doc.rust-lang.org/nightly/std/primitive.tuple.html)[IpAddr](https://doc.rust-lang.org/nightly/std/net/enum.IpAddr.html), [u16](https://doc.rust-lang.org/nightly/std/primitive.u16.html)[)](https://doc.rust-lang.org/nightly/std/primitive.tuple.html)
* impl<K, V> [FromIterator](https://notriddle.com/notriddle-rustdoc-test/std/iter/trait.FromIterator.html)<[(](https://notriddle.com/notriddle-rustdoc-test/std/primitive.tuple.html)K, V[)](https://notriddle.com/notriddle-rustdoc-test/std/primitive.tuple.html)> for [BTreeMap](https://notriddle.com/notriddle-rustdoc-test/std/collections/struct.BTreeMap.html)<K, V>

once cell renamings
This PR does the renamings proposed in https://github.com/rust-lang/rust/issues/74465#issuecomment-1153703128
- Move/rename `lazy::{OnceCell, Lazy}` to `cell::{OnceCell, LazyCell}`
- Move/rename `lazy::{SyncOnceCell, SyncLazy}` to `sync::{OnceLock, LazyLock}`
(I used `Lazy...` instead of `...Lazy` as it seems to be more consistent, easier to pronounce, etc)

Improve the tuple and unit trait docs
* Reduce duplicate impls; show only the `(T,)` and include a sentence saying that there exists ones up to twelve of them.
* Show `Copy` and `Clone`.

Here's the new version:

Fix generic impl rustdoc json output
Fixes #97986.
The problem in case of generic trait impl is that the trait's items are the same for all the types afterward. But since they're the same, it's safe for rustdoc-json to just ignore them.
A little representation of what's going on:
```rust
trait T {
fn f(); // <- defid 0
}
impl<Y> T for Y {
fn f() {} // <- defid 1
}
struct S; // <- defid 1 (since it matches `impl<Y> T for Y`
```

Rename rustc_serialize::opaque::Encoder as MemEncoder.
This avoids the name clash with `rustc_serialize::Encoder` (a trait),
and allows lots qualifiers to be removed and imports to be simplified
(e.g. fewer `as` imports).

rustdoc: remove link on slice brackets
This is #91778, take two.
Fixes #91173
The reason I'm reevaluating this change is #97668, which makes fully-generic slices link to the slice docs page. This fixes some downsides in the original PR, where `Box<[T]>`, for example, was not linked to the primitive.slice.html page. In this PR, the `[T]` inside is still a link.
The other major reason for wanting to reevaluate this is the changed color scheme. When this feature was first introduced in rustdoc, primitives were a different color from structs and enums. This way, eagle-eyed users could figure out that the square brackets were separate links from the structs inside. Now, all types have the same color, so a significant fraction of users won't even know the links are there unless they pay close attention to the status bar or use an accessibility tool that lists all links on the page.
