This commit adds a test case for generics, re-adds generics data
to the search index, and tweaks function indexing to use less space in JSON.
This reverts commit 14ca89446c.
Properly render HRTBs
```rust
pub fn test<T>()
where
for<'a> &'a T: Iterator,
{}
```
This will now render properly including the `for<'a>`
I do not know if this covers all cases, it only covers everything that I could think of that includes `for` and lifetimes in where bounds.
Also someone need to mentor me on how to add a proper rustdoc test for this.
Resolves#78482
rustdoc: add optional woff2 versions of Source Serif and Source Code
This provides woff2 versions of Source Serif and Source Code similar to how #82545 provides woff2 versions of Fira Sans. The total byte count for the six files (three for each font family) is reduced by 25% from 476 KiB to 358 KiB.
Use Tera templates for rustdoc.
Replaces a format!() call in layout::render with a template
expansion. Introduces a `templates` field in SharedContext so parts
of rustdoc can share pre-rendered templates.
This currently builds in a copy of the single template available, like
with static files. However, future work can make this live-loadable with
a perma-unstable flag, to make rustdoc developers' work easier.
Part of #84419.

These were previously removed along with the details in the
"Implementors" section of trait pages. But for "Implementations on
Foreign Types," we need to include the details because they will not be
documented anywhere else.
That means it will be visible under "Implementors" on trait pages, and
under "Implementations" on struct/enum pages, even when all methods are
collapsed.
Switch to a float layout for rightside elements.
These were hidden by default, and duplicated information already on the
page anyhow.
Also remove the "Auto-hide trait implementors of a trait" setting,
which is not needed anymore.
Remove must_use from ALLOWED_ATTRIBUTES
This is a fairly common attribute on methods, but is not something you need to know when reading the method docs - the purpose of the attribute is for the compiler to tell you about it if you forget to use a value.
Removing reclaims some valuable space in the summary of methods, particularly when the attribute has a long string value.
As discussed in #84309. Partially addresses #81482.

rustdoc: revert deref recur to resume inclusion of impl ExtTrait<Local> for ExtType
As discussed here: https://github.com/rust-lang/rust/issues/82465#issuecomment-829290384, Revert PR #80653 to resolve issue #82465.
Issue #82465 was we had stopped including certain trait implementations, namely implementations on an imported type of an imported trait *instantiated on a local type*. That bug was injected by PR #80653.
Reverting #80653 means we don't list all the methods that you have accessible via recursively applying `Deref`.
[Discussion in last week's rustc triage meeting](https://zulip-archive.rust-lang.org/238009tcompilermeetings/19557weekly2021042954818.html#236680594) led us to conclude that the bug was worse than the enhancement, and there was not an obvious fix for the bug itself. So for the short term we remove the enhancement, while in the long term we will work on figuring out a way to have our imported trait implementation cake and eat it too.
