## Description
This adds labels to the icons and moves them away from the search box.
These changes are made together, because they work together, but are based on several complaints:
* The [+/-] thing are a Reddit-ism. They don't look like buttons, but look like syntax <https://rust-lang.zulipchat.com/#narrow/stream/266220-t-rustdoc/topic/More.20visual.20difference.20for.20the.20.2B.2F-.20.20Icons>, <https://github.com/rust-lang/rust/issues/59851> (some of these are laundry lists with more suggestions, but they all mention [+/-] looking wrong)
* The settings, help, and summary buttons are also too hard to recognize <https://lwn.net/Articles/987070/>, <https://github.com/rust-lang/rust/issues/90310>, <https://github.com/rust-lang/rust/issues/14475#issuecomment-274241997>, <https://internals.rust-lang.org/t/improve-rustdoc-design/12758> ("Not all functionality is self-explanatory, for example the [+] button in the top right corner, the theme picker or the settings button.")
The toggle-all and toggle-individual buttons both need done at once, since we want them to look like they go together. This changes them from both being [+/-] to both being arrows.
CC <https://github.com/rust-lang/rust/pull/113074#issuecomment-1677469680> and ``@jsha`` regarding the use of triangles for disclosure, which is what everyone wanted, but was pending a good toggle-all button. This PR adds a toggle-all button that should work.
Settings and Help are also migrated, so that the whole group can benefit from being described using actual words.
The breadcrumbs also get redesigned, so that they use less space, by shrinking the parent module path parts. This is done at the same time as the toolbar redesign because it's, effectively, moving space from the toolbar to the breadcrumbs.
This is aimed at avoiding any line wrapping at desktop sizes.
## Prior art
This style of toolbar, with explicit labels on the buttons, used to be more popular. It's not very common in web browsers nowadays, and for truly universal icons like :arrow_left: I can understand why, but words are great when icons fail.

Remove macOS 10.10 dynamic linker bug workaround
Rust's current minimum macOS version is 10.12, so the hack can be removed. This PR also updates the `remove_dir_all` docs to reflect that all supported macOS versions are protected against TOCTOU race conditions (the fallback implementation was already removed in #127683).

`pal::unsupported::process::ExitCode`: use an `u8` instead of a `bool`
`ExitCode` should “represents the status code the current process can return to its parent under normal termination”, but is currently represented as a `bool` on unsupported platforms, making the `impl From<u8> for ExitCode` lossy.
Fixes #130532.
History: [IRLO thread](https://internals.rust-lang.org/t/mini-pre-rfc-redesigning-process-exitstatus/5426) (`ExitCode` as a `main` return), #48618 (initial impl), #93445 (`From<u8>` impl).

Win: Open dir for sync access in remove_dir_all
A small follow up to #129800.
We should explicitly open directories for synchronous access. We ultimately use `GetFileInformationByHandleEx` to read directories which should paper over any issues caused by using async directory reads (or else return an error) but it's better to do the right thing in the first place. Note though that `delete` does not read or write any data so it's not necessary there.

Add `Thread::{into_raw, from_raw}`
Public API:
```rust
#![unstable(feature = "thread_raw", issue = "97523")]
impl Thread {
pub fn into_raw(self) -> *const ();
pub unsafe fn from_raw(ptr: *const ()) -> Thread;
}
```

In the implementation of `force_mut`, I chose performance over safety.
For `LazyLock` this isn't really a choice; the code has to be unsafe.
But for `LazyCell`, we can have a full-safe implementation, but it will
be a bit less performant, so I went with the unsafe approach.

fix: Remove duplicate `LazyLock` example.
The top-level docs for `LazyLock` included two lines of code, each with an accompanying comment, that were identical and with nearly- identical comments. This looks like an oversight from a past edit which was perhaps trying to rewrite an existing example but ended up duplicating rather than replacing, though I haven't gone back through the Git history to check.
This commit removes what I personally think is the less-clear of the two examples.

[library/std/src/process.rs] `PartialEq` for `ExitCode`
Converting a third-party CLI to a library so started passing around [`std::process::ExitCode`](https://doc.rust-lang.org/std/process/struct.ExitCode.html) in an `Either`. Then I realised the tests can't be modified to compare equality of `ExitCode`s.
This PR fixes this oversight.

Documentation comments for `catch_unwind` and `thread::join` to indicate
new behavioral guarantee when catching a foreign exception.

Add `core::panic::abort_unwind`
`abort_unwind` is like `catch_unwind` except that it aborts the process if it unwinds, using the `#[rustc_nounwind]` mechanism also used by `extern "C" fn` to abort unwinding. The docs attempt to make it clear when to (rarely) and when not to (usually) use the function.
Although usage of the function is discouraged, having it available will help to normalize the experience when abort_unwind shims are hit, as opposed to the current ecosystem where there exist multiple common patterns for converting unwinding into a process abort.
For further information and justification, see the linked ACP.
