[rustdoc] Fix crates filtering box not being filled
Currently, the filter crate box (at the left of the search input) is always empty. To get the number of keys of dictionary in JS, you need to call `Object.keys()` on it.

Simplify foreign type rendering.
Simplified foreign type rendering by switching from tables to flexbox. Also, removed some seemingly extraneous elements like “ghost” spans.
Reduces element count on the `std::iter::Iterator` page by 30%. On my laptop it drops Iterator page load time from ~15s to ~10s. Frame times during scrolling are a hair lower too.
Known visual changes (happy to tweak based on feedback):
* The main `impl ...` headers are now getting the default, larger, h3 font size. This was an accident, but I liked how it turned out so I didn't fix it.
* There's a hair less vertical spacing between the end of a where block and the start of the next fn. Now, all spacing is consistent. I think this looks a bit worse. I may tweak vertical spacing more here or in a follow-up that cleans up vertical spacing more broadly.
* "[src]" links are all sized at 17px. A few were 19px in the original.
I haven't yet done heavy cross-browser or cross-crate testing. I was hoping to get a quick thumbs up or thumbs down here at this first draft, then if this is on the right track I'll spend some time on that testing.

Use fonts from the Roman 2.007 and Italic 1.007 version at:
https://github.com/adobe-fonts/source-serif-pro/releases/tag/2.007R-ro%2F1.007R-it
The following files are used from the distribution:
* WOFF/TTF/SourceSerifPro-Regular.ttf.woff
* WOFF/TTF/SourceSerifPro-Bold.ttf.woff
* WOFF/TTF/SourceSerifPro-It.ttf.woff
These replace the older Source Serif Pro regular and bold fonts, and
the Heuristica italic font.

rustdoc: add new CLI flag to load static files from a different location
This PR adds a new CLI flag to rustdoc, `--static-root-path`, which controls how rustdoc links pages to the CSS/JS/font static files bundled with the output. By default, these files are linked with a series of `../` which is calculated per-page to link it to the documentation root - i.e. a relative link to the directory given by `-o`. This is causing problems for docs.rs, because even though docs.rs has saved one copy of these files and is dispatching them dynamically, browsers have no way of knowing that these are the same files and can cache them. This can allow it to link these files as, for example, `/rustdoc.css` instead of `../../rustdoc.css`, creating a single location that the files are loaded from.
I made sure to only change links for the *static* files, those that don't change between crates. Files like the search index, aliases, the source files listing, etc, are still linked with relative links.

Greatly improve rustdoc rendering speed issues
Fixes#55900.
So a few improvements here:
* we're switching to `DOMTokenList` API when available providing a replacement if it isn't (should only happen on safari and IE I think...)
* hide doc sections by default to allow the whole HTML generation to happen in the background to avoid triggering DOM redraw all the times (which killed the performances)

rustdoc: Fix local reexports of proc macros
Filter out `ProcMacroStub`s to avoid an ICE during cleaning.
Also add proc macros to `cache().paths` so it can generate links.
r? @QuietMisdreavus
This commit replaces many usages of `File::open` and reading or writing
with `fs::read_to_string`, `fs::read` and `fs::write`. This reduces code
complexity, and will improve performance for most reads, since the
functions allocate the buffer to be the size of the file.
I believe that this commit will not impact behavior in any way, so some
matches will check the error kind in case the file was not valid UTF-8.
Some of these cases may not actually care about the error.
Replace usages of `..i + 1` ranges with `..=i`.
Before this change we were using old computer code techniques. After this change we use the new and improved computer code techniques.
