Fix search result bottom border color
It reverts a color change while keeping the improvement made in #103938.
I think it'll need to be backported once merged too.

rustdoc: add hash to filename of toolchain files
All static files used by rustdoc are now stored in static.files/ and their filenames include a hash of their contents. Their filenames no longer include the contents of the --resource-suffix flag. This clarifies caching semantics. Anything in static.files can use Cache-Control: immutable because any updates will show up as a new URL.
Invocation-specific files like crates-NN.js, search-index-NN.js, and sidebar-items-NN.js still get the resource suffix.
This has a useful side effect: once toolchain files aren't affected by resource suffix, it will become possible for docs.rs to include crate version in the resource suffix. That should fix a caching issue with `/latest/` URLs: https://github.com/rust-lang/docs.rs/issues/1593. My goal is that it should be safe to serve all rustdoc JS, CSS, and fonts with infinite caching headers, even when new versions of a crate are uploaded in the same place as old versions.
The --disable-minification flag is removed because it would vary the output of static files based on invocation flags. Instead, for rustdoc development purposes it's preferable to symlink static files to a non-minified copy for quick iteration.

Fixes#98413
rustdoc: remove unused mobile CSS `.rustdoc { padding-top: 0 }`
When this rule was added in dd437ee6ed, as `body { padding-top: 0 }`, the desktop body tag had non-zero top padding. This padding was removed in 135281ed15.
This rule no longer overrides a rule in rustdoc's desktop styles, and also doesn't override the UA stylesheet, since the [HTML standard] has only margin, not padding, on the page body.

Using flexbox in column direction is needlessly complicated, since no
special flex powers are being used here. Just use regular block layout.
This should result in no visible changes.
rustdoc: clean up `#toggle-all-docs`
This change converts the element from an `<a>` link to a button. It's pretty much directly trading slightly more CSS for slightly less HTML, and it's also semantically correct (so you don't get a broken "bookmark" option when you right click on it).
While doing this, I also got rid of the unnecessary `class="inner"` attribute on the inner span. There was a style targeting `.collapse-toggle > .inner`, but no CSS ever targeted the `#toggle-all-docs > .inner`.

rustdoc: remove unnecessary CSS `.search-results { padding-bottom }`
There's nothing underneath it anyway. The conversation on #84462 never really spelled out why it was added.

rustdoc: stop hiding focus outlines on non-rustdoc-toggle details tags
We really shouldn't be overriding this kind of stuff unless the browser default is really broken (like outlining the thing that isn't clickable). This directly reverts b8f4e74cbc.
This wrapper DIV was originally added in
89e1fb3223, when it allowed the search bar's
size to be calculated without using `calc()`. This `width` hack can be
removed using flexbox.

default is really broken (like outlining the thing that isn't clickable).
This directly reverts b8f4e74cbc.
The change in opacity is inconsistent with most of rustdoc, which uses
default browser styles for the focus outline. Unfortunately, just using
the default focus outline here won't work, because it gets applied to
the summary itself instead of the pseudo-element "real button."
rustdoc: remove redundant CSS `a.test-arrow:hover`
In 4b402dbe69, when this rule was added, it was overriding a rule that made all links in docblock get an underline when hovered. This became redundant when, after reordering the rules, 7585632052 changed the pro-underline rule to exclude the test-arrow link anyway.

rustdoc: remove no-op CSS `.code-header { border-bottom: none }`
The code headers are always h3 or h4, which don't have border-bottom by default anyway.
