Remove `DefPath` from `Visibility` and calculate it on demand
Depends on #80090 and should not be merged before. Helps with https://github.com/rust-lang/rust/issues/79103 and https://github.com/rust-lang/rust/issues/76382.
cc https://github.com/rust-lang/rust/pull/80014#issuecomment-746810284 - `@nnethercote` I figured it out! It was simpler than I expected :)
This brings the size of `clean::Visibility` down from 40 bytes to 8.
Note that this does *not* remove `clean::Visibility`, even though it's now basically the same as `ty::Visibility`, because the `Invsible` variant means something different from `Inherited` and I thought it would be be confusing to merge the two. See the new comments on `impl Clean for ty::Visibility` for details.
This function was unfortunate for several reasons:
- It used `unsafe` because it wanted to tell whether a string came from
the same *allocation* as another, not just whether it was a textual
match.
- It recalculated spans even though they were already available from
pulldown
- It sometimes *failed* to calculate the span, which meant it was always
possible for the span to be `None`, even though in practice that
should never happen.
This commit has several cleanups:
- Make the span required
- Pass through the span from pulldown in the `HeadingLinks` and
`Footnotes` iterators
- Only add iterator bounds on the `impl Iterator`, not on `new` and the
struct itself.
Continue String to Symbol conversion in rustdoc (2)
Follow-up of #80119.
This is the last one (and I actually expected more conversions but seems like it was the last one remaining...).

Continue String to Symbol conversion in rustdoc

This PR is already big enough so I'll stop here before the next one.

Use more symbols in rustdoc
Builds on https://github.com/rust-lang/rust/pull/80044 and should not be merged before.
I want to test if this is actually faster before merging it, there was a lot of `to_string()` calls so I'm not sure it will actually help. That means I have to wait for 80044 to get merged before running perf.

[rustdoc] Switch to Symbol for item.name
This decreases the size of `Item` from 680 to 616 bytes. It also does a
lot less work since it no longer has to copy as much.
Helps with #79103.

Fixes submit event of the search input
Fixes https://github.com/rust-lang/rust/issues/79960
It's a very funny corner case:
In HTML, when a button follows an input (in a `form`), if the enter keep is pressed on the input, instead of sending the submit event to the input, it'll create a click event on the button following it, which in this case made the help popup show up whenever "enter" was pressed.

rustdoc light theme: Fix CSS for selected buttons
Fixes#79961.
The background was dark before, which made the text impossible to read.
Now the button doesn't override the background, and the only thing it
does is add a light-blue top border.
Ultimately, the search results tabs now look very similar to how they
used to look.

In HTML, when a button follows an input, if the enter keep is pressed on the input, instead of sending the submit event to the input, it'll create a click event on the button following it, which in this case made the help popup show up whenever "enter" was pressed.
The background was dark before, which made the text impossible to read.
Now the background is white, which is how selected `div`s are rendered.
As a result, the search results tabs now look identical to how they
used to look (before #79896).
[rustdoc] Calculate span information on demand instead of storing it ahead of time
This brings `size_of<clean::types::Span>()` down from over 100 bytes (!!) to only 12, the same as rustc. It brings `Item` down even more, from `784` to `680`.
~~TODO: I need to figure out how to do this for the JSON backend too. That uses `From` impls everywhere, which don't allow passing in the `Session` as an argument. `@P1n3appl3,` `@tmandry,` maybe one of you have ideas?~~ Figured it out, fortunately only two functions needed to be changed. I like the `convert_x()` format better than `From` everywhere but I'm open to feedback.

Make search results tab and help button focusable with keyboard
Fixes https://github.com/rust-lang/rust/issues/79859.
I replaced the element with `button` tag, which allows to focus them (and "click" on them using "enter") using only the keyboard.

Dogfood `str_split_once()`
Part of https://github.com/rust-lang/rust/issues/74773.
Beyond increased clarity, this fixes some instances of a common confusion with how `splitn(2)` behaves: the first element will always be `Some()`, regardless of the delimiter, and even if the value is empty.
Given this code:
```rust
fn main() {
let val = "...";
let mut iter = val.splitn(2, '=');
println!("Input: {:?}, first: {:?}, second: {:?}", val, iter.next(), iter.next());
}
```
We get:
```
Input: "no_delimiter", first: Some("no_delimiter"), second: None
Input: "k=v", first: Some("k"), second: Some("v")
Input: "=", first: Some(""), second: Some("")
```
Using `str_split_once()` makes more clear what happens when the delimiter is not found.
Remove tab-lock and replace it with ctrl+up/down arrows to switch between search result tabs
Fixes https://github.com/rust-lang/rust/issues/65212
What took the longest time was to update the help popup in the end.
