Merge settings.css into rustdoc.css #115812

Merged

There aren't that many CSS rules in settings.css, however quite some code is needed around it, making it more costly than useful. I think it's better to merge into rustdoc.css to simplify this.

Removed the loadCss completely as it's not used anywhere.

This does simplify things a lot, and I was thinking of doing the same thing.

But I wonder if it might instead be helpful to rename settings.css to extra.css, pull the search engine stylesheet rules into it, have search.js load it, and have it get preloaded when you click the search bar? The annoying part about merging everything into rustdoc.css is that it needs to get loaded before first contentful paint, so it would be nice to keep stuff that isn't needed for that out in separate files.

The big being: is it really worth it? I think the perf impact is close to non-existent here. If we start having pages that have their own specific style and enough to make it actually worth it to put them into their own files, could be worth a try. Currently it's not the case as far as I can see.

Good point. It looks like, if we want to improve the TTFP, our best bet is to look at themes (light.css is the last stylesheet to load).

Having them in separate files used to make more sense, before the
migration to CSS variables made the theme files as small as they are
nowadays. This is already how docs.rs and mdBook do it.
