Add margin after doc search results
I found it not really on computer that the last result is right at the bottom of the page. I find it better with margin below (especially when you hover the last element!). A screenshot to show the result:

This causes the components of FQN's to behave similarly to other links
in the contents of rustdoc-styled pages.
I (and I hope others at least in part) have found the prior design to be
somewhat confusing, as it is not clear (upon hovering) that the various
parts of the FQN are actually links that the user can navigate to.
In short, this patch makes links in the FQN have an underline when the
user hovers over them, more clearly indicating that they can be used for
navigation.

Previously, compile_fail and ignore code examples displayed a tooltip
indicating this in the documentation. This tooltip has now also been
added to should_panic examples.
Unblock font loading in rustdoc.css
rustdoc's font loading defaults to "auto", so browsers may block render.
But rustdoc's case prefers a faster TTI for scrolling, this means the
strictest font-display in use should be "swap". rustdoc's fonts do provide
notable legibility improvements but first-time users will have little trouble
reading without. This means "optional" is preferred.
The one exception is Source Serif Pro: it's a big difference for body text, so
"fallback" is preferred over "optional" to cause a (tiny) block.
This follows up on (but does not resolve) #20962, taking PageSpeed Insight's rec fairly directly. Supporting reading material: https://drafts.csswg.org/css-fonts-4/#font-display-desc

Preserve whitespace inside one-backtick codeblocks
Previously this was only done inside short docblocks (e.g., summary
lines), but we should also do so in general.
Fixes#65555
rustdoc: fixes#64305: disable search field instead of hidding it
The result seems to be ok but I wasn't entirely sure how to get there. I tried to stay generic a bit but maybe it's not required at all.
