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.
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).
Fix invalid line number match
If a code line is longer than the width, it then gets to the next line making the line number not matching it anymore.
r? @QuietMisdreavus
emit error when doc generation fails
Fixes#41813.
The diagnostic looks something like this:
```
error: couldn't generate documentation: No space left on device (os error 28)
|
= note: failed to create or modify "/path/to/crate/target/doc/src/lazycell"
```

Remove not used `DotEq` token
Currently libproc_macro does not use `DotEq` token.
https://github.com/rust-lang/rust/pull/49545 changed libproc_macro
to not generate `DotEq` token.
set to zero meant that the nested list was squished up against
subsequent list items/paragraphs
this changes the bottom margin to .6em, same as for paragraphs
an example demonstrating the difference with screenshots is given in the
pull request
