rustdoc: Finalize dyn compatibility renaming
Update the Reference link to use the new URL fragment from https://github.com/rust-lang/reference/pull/1666 (this change has finally hit stable). Fixes a FIXME.
Follow-up to #131594.
Part of #130852.

Update the `wasm-component-ld` tool
This commit updates the `wasm-component-ld` tool from 0.5.11 to 0.5.12. This pulls in a fix for the binary adapters that are included with this tool for an issue described in bytecodealliance/wasmtime#10058. Some other dependencies have additionally been updated in the meantime of `wasm-component-ld` but there should otherwise be no major changes.

Before, the LTO configuration from `config.toml` was not applied to `rustdoc`.

= note: this error originates in the macro `include` (in Nightly builds, run with -Z macro-backtrace for more info)
```
When we attempt to load a Rust source code file, if there is a OS file failure we try reading the file as bytes. If that succeeds we try to turn it into UTF-8. If *that* fails, we provide additional context about *where* the file has the first invalid UTF-8 character.
Fix #76869.

tests: delete `cat-and-grep-sanity-check`
Part of #121876.
All remaining `Makefile`s have open PRs that do not rely on platform `cat` or `grep` or the `cat-and-grep` script.

Move `supertrait_def_ids` into the elaborate module like all other fns
It's strange that this is the only elaborate-like fn on tcx.

CI: build FreeBSD artifacts on FreeBSD 13.4
13.2 is EoL, and 13.3 will be EoL too in about 2 months. Plus, both suffer from a bug in LLVM's libunwind. It causes a segfault inside of std::backtrace::Backtrace::capture().
Fixes #132185
cc ``````@ehuss`````` . before you can do the trybuild, you'll also have to download new FreeBSD 13.4 base.txz images and place them in https://ci-mirrors.rust-lang.org/rustc , then update this PR with the correct file names.

bump compiler and tools to windows 0.59, bootstrap to 0.57
This bumps compiler and tools to windows 0.59 (temporary dupes version, as `sysinfo` still depend on <= 0.57).
Bootstrap bumps only to 0.57 (the same sysinfo dep).
This additionally resolves my comment https://github.com/rust-lang/rust/pull/130874#issuecomment-2393562071
Will work on it in follow up pr: There still some sus imports for `rustc_driver.dll` like ws2_32 or RoOriginateErrorW, but i will look at them later.

- Improve the discussion of `unsafe` blocks within `unsafe` functions.
- Fix formatting in Appendix A
|
|
Ensure that all the fields that rust-analyzer understands are in the
manual, they all have doc comments, and they use consistent
punctuation (`;` rather than mixing `,` and `;`).
Whilst we're here, fix the `sysroot_src` example and add 2024 as a
legal value for Rust edition.

remove support for the (unstable) #[start] attribute
As explained by `@Noratrieb:`
`#[start]` should be deleted. It's nothing but an accidentally leaked implementation detail that's a not very useful mix between "portable" entrypoint logic and bad abstraction.
I think the way the stable user-facing entrypoint should work (and works today on stable) is pretty simple:
- `std`-using cross-platform programs should use `fn main()`. the compiler, together with `std`, will then ensure that code ends up at `main` (by having a platform-specific entrypoint that gets directed through `lang_start` in `std` to `main` - but that's just an implementation detail)
- `no_std` platform-specific programs should use `#![no_main]` and define their own platform-specific entrypoint symbol with `#[no_mangle]`, like `main`, `_start`, `WinMain` or `my_embedded_platform_wants_to_start_here`. most of them only support a single platform anyways, and need cfg for the different platform's ways of passing arguments or other things *anyways*
`#[start]` is in a super weird position of being neither of those two. It tries to pretend that it's cross-platform, but its signature is a total lie. Those arguments are just stubbed out to zero on ~~Windows~~ wasm, for example. It also only handles the platform-specific entrypoints for a few platforms that are supported by `std`, like Windows or Unix-likes. `my_embedded_platform_wants_to_start_here` can't use it, and neither could a libc-less Linux program.
So we have an attribute that only works in some cases anyways, that has a signature that's a total lie (and a signature that, as I might want to add, has changed recently, and that I definitely would not be comfortable giving *any* stability guarantees on), and where there's a pretty easy way to get things working without it in the first place.
Note that this feature has **not** been RFCed in the first place.
*This comment was posted [in May](https://github.com/rust-lang/rust/issues/29633#issuecomment-2088596042) and so far nobody spoke up in that issue with a usecase that would require keeping the attribute.*

If the user doesn't have rustc on $PATH, rust-analyzer won't be able
to run `rustc --print cfg`. This isn't really an error, as
rust-analyzer can still proceed without it.
This is particularly noticeable when loading crates defined in a
rust-project.json. Until the configuration is loaded, the opened files
are briefly treated as detached files and users see this error.
Environments with rust-project.json generally have a sysroot and rustc
elsewhere, so the error confuses users.

I don't think my ranking is perfect, because it places them even behind snippet completions, but this is something.
