rustdoc: clean up tuple <-> primitive conversion docs
This adds a minor missing feature to `fake_variadic`, so that it can render `impl From<(T,)> for [T; 1]` correctly.

Fix extern crates not being hidden with `doc(hidden)`
Fixes#126796.
Only the current crate should never be stripped, any other crate should be strippable.

modularize rustdoc's write_shared
Refactor src/librustdoc/html/render/write_shared.rs to reduce code duplication, adding unit tests
* Extract + unit test code for sorting and rendering JSON, which is duplicated 9 times in the current impl
* Extract + unit test code for encoding JSON as single quoted strings, which is duplicated twice in the current impl
* Unit tests for cross-crate information file formats
* Generic interface to add new kinds of cross-crate information files in the future
* Intended to match current behavior exactly, except for a merge info comment it adds to the bottom of cci files
* This PR is intended to reduce the review burden from my [mergeable rustdoc rfc](https://github.com/rust-lang/rfcs/pull/3662) implementation PR, which is a [small commit based on this branch](https://github.com/EtomicBomb/rust/tree/rfc). This code is agnostic to the RFC and does not include any of the flags discussed there, but cleanly enables the addition of these flags in the future because it is more modular
This approach is, roughly, based on how Discourse does it.
It came up while discussing some other possible sidebar changes,
as a design that made rapid scanning easier while avoiding the
inherent trade-offs in summarizing.
Use `FnSig` instead of raw `FnDecl` for `ForeignItemKind::Fn`, fix ICE for `Fn` trait error on safe foreign fn
Let's use `hir::FnSig` instead of `hir::FnDecl + hir::Safety` for `ForeignItemKind::Fn`. This consolidates some handling code between normal fns and foreign fns.
Separetly, fix an ICE where we weren't handling `Fn` trait errors for safe foreign fns.
If perf is bad for the first commit, I can rework the ICE fix to not rely on it. But if perf is good, I prefer we fix and clean up things all at once 👍

Remove useless attributes in merged doctest generated code
I took another look at the generated code for merged doctests and it seems like those attributes are only useful when running `rustc --test`, which isn't the case for merged doctests. Less code generated. \o/

Add possibility to generate rustdoc JSON output to stdout
Fixes#127165.
I think it's likely common to want to get rustdoc json output directly instead of reading it from a file so I added this option to allow it. It's unstable and only works with `--output-format=json`.

Shrink `TyKind::FnPtr`.
By splitting the `FnSig` within `TyKind::FnPtr` into `FnSigTys` and `FnHeader`, which can be packed more efficiently. This reduces the size of the hot `TyKind` type from 32 bytes to 24 bytes on 64-bit platforms. This reduces peak memory usage by a few percent on some benchmarks. It also reduces cache misses and page faults similarly, though this doesn't translate to clear cycles or wall-time improvements on CI.

Emit a warning instead of an error if `--generate-link-to-definition` is used with other output formats than HTML
Fixes https://github.com/rust-lang/docs.rs/issues/2581.
It's a bit weird to emit an error in this case anyway, a warning is more than enough.
