rustdoc: remove unused CSS `.docblock a:not(.srclink)`
This selector was added in c7312fbae4, because the list of impl items could be nested below `docblock`.
c7312fbae4/src/librustdoc/html/render.rs (L3841-L3845)
Now that rustdoc toggles have been switched to `<details>`, there shouldn't be any need to put things inside docblock containers just to give them disclosure toggles.
rustdoc: remove unused CSS `.content .item-list`
When these rules were added in 4fd061c426 (yeah, that's the very first commit of rustdoc_ng), `.item-list` was a `<ul>`, and this would override the default style for that tag.
In c1b1d6804b, it was changed to use a `<div>` tag, so these rules are both no-ops.

rustdoc: remove font family CSS on `.rustdoc-toggle summary::before`
This rule became irrelevant since c58246efe4 made it so that the `summary::before` pseudo-element contains an SVG instead of text.

# `flex-basis: 100%`
When `.impl-items { flex-basis: 100% }` and `h3.impl, h3.method, h4.method, h3.type, h4.type, h4.associatedconstant` were added in 34bd2b845b, it seems like it was a mistake even then. According to MDN, [flex-basis] does nothing unless the box it's applied to is a flex *item*, a child of a flex container. However, when this was added, these elements were flex containers themselves.

# `position: relative`
This property was added to help with positioning the `[+]/[-]` toggle. It is no longer necessary, because `details.rustdoc-toggle` already has `position:relative` set on it.

Migrate sidebar links color to CSS variables and unify themes with ayu
Part of https://github.com/rust-lang/rust/pull/98460.
This PR does two things:
1. Migrate more theme CSS rules toward CSS variables.
2. Remove `a.current` specific colors depending on the kind of the item behind the link. The `ayu` theme was already doing it this way and I think it makes much more sense like this.
You can test it [here](https://rustdoc.crud.net/imperio/sidebar-links-color/lib2/struct.Foo.html) by hovering other module's items in the sidebar (or check the selector `a.current`).

rustdoc: remove no-op CSS `h3.variant, .sub-variant h4 { border-bottom: none }`
This rule, added in 69df43b041 to override the default `h4` style, has been obsoleted when a65c98fefb changed it so that only the top docblock put `border-bottom` on `h4.`
rustdoc: remove no-op source sidebar `opacity`
These rules were added in dc2c972334 to work with CSS transitions. They're otherwise redundant, since the `visibility` property already hides everything.
dc2c972334/src/librustdoc/html/static/css/rustdoc.css (L350-L354)
The transition was remove with 237d62588d, but the now-redundant `opacity` property was not.
rustdoc: remove unneeded CSS `.rust-example-rendered { position }`
The Run button isn't inside the `<pre>` any more. It's instead nested below the example wrapper.
The class name can't be removed from the DOM, because `main.js` uses it.

rustdoc: remove bad CSS font-weight on `.impl`, `.method`, etc
This line was added in c494a06064, because at the time, the headers had these classes on them. Now, the headers are children of the `<section>` with the class on it.
This commit also adds a test case, to make sure the srclink font weight does not regress again.

These rules were copied from normalize.css 3, and are mostly redundant.
* `optgroup` isn't used in rustdoc at all
* `textarea` is only used for the "copy" button, so it's not visible
* The remaining buttons and inputs mostly have styles set anyway.
* We should never be setting `color` without also setting the
background to something. Otherwise, you get white-on-gray
text. That seems to be [the reason] why `normalize.css` changed this.

rustdoc: remove redundant mobile `.source > .sidebar` CSS
When the source sidebar and standard sidebar had most of their code merged in 07e3f998b1, the properties `z-index: 11`, `margin: 0`, and `position: fixed` were already being set on the `.sidebar` class, so no need to repeat them.

rustdoc: remove redundant `#help-button` CSS
When the separate top and bottom styles were added in cd3f4da244, some of the CSS rules were needlessly duplicated.
The `text-align: initial` rule on `.side-by-side` was always redundant, since the rules that centered the text were set on children, not parents.

When this CSS was added in 34bd2b845b, source links were nested below headers.

Now, thanks to 458e7219bc, they are now siblings of headers, and thanks to 270d09dca9, they have the same font size that they would've had anyway.

This affected layout a little and required adjustments to the CSS to
keep spacing the same. In particular, the margins of adjacent items
usually overlap with each other. However, when an item has contain:
layout, any margins of child nodes push out the size of the item itself.
This was making spacing between items a little too big. To solve that, I
removed margins in some places: in particular for certain classes that
often occur at the end of a `details.rustdoc-toggle` block, I removed
their bottom margin. Generally, the margins provided by the next item
down are sufficient.
Also remove an unnecessary margin-top on .code-header.
