rustdoc: Fix generating redirect pages for statics and consts
These were missing from the cache for some reason meaning the redirect pages failed to render.
print enum variant fields in docs
Right now we are repeating enum variants at the top, because the fields aren't shown with the actual docs. It's very annoying to have to scroll up and down to have both docs and field info. For struct variants we already list the fields.
enum docs look like this after this PR:
There are degenerate cases for enum tuple variants with lots of fields:
I was thinking that we could move the docs below the variant (slightly indented) or list the variant fields vertically instead of horizontally

Changed toggle all sections key to `T`
Allows both `T` and `t`.
It had been [Shift]+[+] before.
In response to #33791.

Added a `rustdoc` shortcut for collapse/expand all
Now when the user presses the "+" key all sections will collapse/expand.
Also added a note to the help screen which describes this behavior.
This required increasing the height of the help screen.
rustdoc: Add doc snippets for trait impls, with a read more link
The read more link only appears if the documentation is more than one line long.
It currently does not appear on non-defaulted methods, since you can document them directly. I could make it so that default documentation gets forwarded if regular docs don't exist.

rustdoc: Make the #[stable(since)] version attribute clearer with a tooltip
Rustdoc's new 'since' version placement only shows the version number in which the item was marked stable. This gains space but might make the meaning of this version string less clear in the docs, so I tried to bring some explicitness in a tooltip.
Remove ExplicitSelf from HIR
`self` argument is already kept in the argument list and can be retrieved from there if necessary, so there's no need for the duplication.
The same changes can be applied to AST, I'll make them in the next breaking batch.
The first commit also improves parsing of method declarations and fixes https://github.com/rust-lang/rust/issues/33413.

rustdoc: add "src" links to individual impls
Since these impls can be scattered around quite a bit, it is nice to be able to jump to the location where individual methods and trait impls are defined.
NOTE: this needs an update to the CSS, which I'd like to leave for whoever is the "rustdoc frontend champion". The new [src] links are currently too large and bold. Also, the interaction with the "since version X" annotations is not good.
Fixes: #30416
rustdoc: refactor rustdoc syntax highlighting for a more flexible API
Clients can now use the rustdoc syntax highlighter to classify tokens, then use that info to put together there own HTML (or whatever), rather than just having static HTML output.

Fixes: #30416
Clients can now use the rustdoc syntax highlighter to classify tokens, then use that info to put together there own HTML (or whatever), rather than just having static HTML output.
Especially in cases like the one in the test file, this can blow
up the docs big time if string constants in the code contain HTML.
But also other constants can contain special chars (e.g. `&` as an
operator in constant expressions).
rustdoc: Cleanup ABI rendering
Use a common method for rendering `extern "<abi>"`.
This now consistently shows `extern fn` rather than `extern "C" fn`.
Make some fatal lexer errors recoverable
I've kept the changes to a minimum since I'm not really sure if this approach is a acceptable.

rustdoc: Handle concurrent mkdir requests
It's likely that `rustdoc` as a tool is run concurrently in the same output
(e.g. documenting multiple crates as Cargo does), in which case it needs to
handle concurrent calls to `fs::create_dir`.
rustdoc: inline all the impls
This used to be done to avoid inlining impls referencing private items, but is now unnecessary since we actually check that impls do not reference non-doc-reachable items.
