spawning thread and the thread being spawned, and that "child" threads
couldn't outlive their parents unless detached, which is incorrect.

The issue seems to stem from rust-lang#87210 where code headings were changed from a heading containing code to a heading with the `code-header` class. `rustdoc.css` was updated, but `ayu.css` was missed.

Constify implementations of `(Try)From` for int types

Added the `Option::unzip()` method

* Adds the `Option::unzip()` method to turn an `Option<(T, U)>` into `(Option<T>, Option<U>)` under the `unzip_option` feature
* Adds tests for both `Option::unzip()` and `Option::zip()`, I noticed that `.zip()` didn't have any
* Adds `#[inline]` to a few of `Option`'s methods that were missing it

correctly handle enum variants in `opt_const_param_of`

Fixes rust-lang#87542

`opt_const_param_of` was returning `None` for args on an enum variant `Enum::Variant::<10>` because we called `generics_of` on the enum variant which has no generics.

Clarify terms in rustdoc book

Fixes rust-lang#70898

I chose to completely remove the term directive over attribute because rustdoc has a lint called `invalid_codeblock_attributes` and the term attributes is used throughout the book. I slightly changed the introductory sentence to describe the relationship between annotations and attributes.

I also moved the text explaining the example from below the blocks to above the blocks which is more in line with the rest of the book. I also changed the description for the `should_panic` attribute as I found it a little confusing. Finally, some of the blocks were `text` and some were `rust` so I changed them all to `text` which is in line with the rest of the book.

typeck: don't suggest inaccessible fields in struct literals and suggest ignoring inaccessible fields in struct patterns

Fixes rust-lang#87872.

This PR adjusts the missing field diagnostic logic in typeck so that when any of the missing fields in a struct literal or pattern is inaccessible then the error is less confusing, even if some of the missing fields are accessible.
