Re-enable history api on file:// protocol
Fixes#57135.
I tested locally on chrome (since it was the browser having issues with history management on `file://` protocol) and it worked fine so I guess we can re-enable it.

[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.

Added a bare-bones eslint config (removing jslint)
This change removes the small bit of jslint config, replacing it
with eslint. I've currently configured eslint to mostly only report
the more serious of lints, although there are still some style nits
turned on.
Eslint better supports modern js, and will be a good pre-TypeScript code
quality aid.
Install eslint with `npm install -g eslint`. Run with `eslint html/static/*.js`,
or let your IDE do it. This requires no build step.
Upcoming changes will start fixing identified bugs and other lints (mostly unused and var redef issues).

rustdoc: give proc-macros their own pages
related to https://github.com/rust-lang/rust/issues/49553 but i don't think it'll fix it
Currently, rustdoc doesn't expose proc-macros all that well. In the source crate, only their definition function is exposed, but when re-exported, they're treated as a macro! This is an awkward situation in all accounts. This PR checks functions to see whether they have any of `#[proc_macro]`, `#[proc_macro_attribute]`, or `#[proc_macro_derive]`, and exposes them as macros instead. In addition, attributes and derives are exposed differently than other macros, getting their own item-type, CSS class, and module heading.
Function-like proc-macros are lumped in with `macro_rules!` macros, but they get a different declaration block (i'm open to tweaking this, it's just what i thought of given how function-proc-macros operate):
Proc-macro attributes and derives get their own pages, with a representative declaration block. Derive macros also show off their helper attributes:
There's one wrinkle which this PR doesn't address, which is why i didn't mark this as fixing the linked issue. Currently, proc-macros don't expose their attributes or source span across crates, so while rustdoc knows they exist, that's about all the information it gets. This leads to an "inlined" macro that has absolutely no docs on it, and no `[src]` link to show you where it was declared.
The way i got around it was to keep proc-macro re-export disabled, since we do get enough information across crates to properly link to the source page:
Until we can get a proc-macro's docs (and ideally also its source span) across crates, i believe this is the best way forward.
