Cleanup markdown span handling
1. Get rid of `locate()` in markdown handling
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 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.
2. Remove unnecessary scope in `markdown_links`
I recommend reading a single commit at a time.
cc ``@bugadani`` - this will conflict with https://github.com/rust-lang/rust/pull/77859, I'll try to make sure that gets merged first.

Make BoundRegion have a kind of BoungRegionKind
Split from #76814
Also includes making `replace_escaping_bound_vars` only return `T`

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
Follow-up of https://github.com/rust-lang/rust/pull/80091.
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.

Don't look for blanket impls in intra-doc links
This never worked and has been causing severe performance problems.
Hopefully it will be re-landed at some point in the future when it
actually works, but in the meantime it makes no sense to have the code
around when it does nothing and actively makes rustdoc harder to use.
Closes https://github.com/rust-lang/rust/issues/78761. Does *not* affect https://github.com/rust-lang/rust/issues/78800.

[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.

This was always questionable, and removing it doesn't fail any tests, so
I think this was not affecting the behavior. It dates all the way back
to the very first commit of rustdoc: 268f3f0ff5
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.
