Add more doc-valid-idents
* "AccessKit" is a commonly used accessibility toolkit used in Rust GUIs.
* "CoreFoundation", "CoreGraphics", "CoreText" are frameworks on Apple OSes.
* "Direct2D", "Direct3D", "DirectWrite" are frameworks on Windows
* "PostScript" is a programming language and is mentioned when talking about text and vector graphics.
* "OpenAL" is an audio framework / API.
* "OpenType" is a font format (TrueType is already mentioned).
* "WebRTC", "WebSocket", "WebTransport" are web networking technologies.
* "NetBSD" and "OpenBSD" are like the already included FreeBSD.
changelog: [`doc_markdown`]: Add AccessKit, CoreFoundation, CoreGraphics, CoreText, Direct2D, Direct3D, DirectWrite, PostScript, OpenAL, OpenType, WebRTC, WebSocket, WebTransport, NetBSD, and OpenBSD to `doc-valid-idents`.

Fix and rename `overflow_check_conditional`
fixes#2457
Other changes:
* Limit the lint to unsigned types.
* Actually check if the operands are the same rather than using only the first part of the path.
* Allow the repeated expression to be anything as long as there are no side effects.
changelog: Rename `overflow_check_conditional` to `panicking_overflow_check` and move to `correctness`
Fix guidance of [`float_cmp`] and [`float_cmp_const`] to not incorrectly recommend `f__::EPSILON` as the error margin.
Using `f32::EPSILON` or `f64::EPSILON` as the floating-point equality comparison error margin is incorrect, yet `float_cmp` has until now recommended this be done. This change fixes the given guidance (both in docs and compiler hints) to not reference these unsuitable constants.
Instead, the guidance now clarifies that the scenarios in which an absolute error margin is usable, provides a sample implementation for using a user-defined absolute error margin (as an absolute error margin can only be used-defined and may be different for different comparisons) and references the floating point guide for a reference implementation of relative error based equality comparison for cases where absolute error margins cannot be identified.

Lintcheck: Refactor structs and only take one version per crate
For some time now I had the feeling that lintcheck's main file has been too large. This PR simply moves some structs into new submodules.
I've also changed the `.toml` structure slightly to only accept one version per crate. AFAIK, we haven't use multiple versions before. If we want to test different versions, we can simply just add a second entry. That's what lintcheck does internally anyways.
I wanted to have these changes in separate commits, but then accidentally squashed them... So sorry 😅

r? `@Alexendoo` If you think this is not really worth a proper review, since it's mostly a move refactoring in an internal tool, you can also `r=xFrednet` on this PR.

This lint makes Clippy warn about situations where an owned
struct is essentially recreated by moving all its fields into a
new instance of the struct. Until now this lint only triggered
for structs recreated from a base struct.
NB: The new functionality too will cause false positives for the
situation where a non-copy struct consisting of all copy members
is touched again in subsequent code.

Remove internal `compiler_lint_functions` lint
This internal lint has effectively been superseded by `disallowed_methods` when we started using that in #11811 (I didn't even know that we also had this internal lint at the time of when I created that PR).
Some of the methods that this looks for also don't exist anymore (`span_lint_note` and `span_lint_help`), though there was one that that lint had but wasn't disallowed in clippy.toml (`LintContext::lint`)

Refactor `assigning_clones`
Short list of changes:
* Inline and simplify `extract_call`
* Inline `is_ok_to_suggest`
* Inline `skip_drop_block`
* Check the HIR tree before the macro check
* Don't call `outer_expn_data`
* Use `find` instead of a loop in `clone_source_borrows_from_dest`

`significant_drop_in_scrutinee`: Trigger lint also for scrutinees in `while let` and `if let`
This lint should also work for `if let` and `while let`, so this PR makes it actually work.
For `while let`, I can't think of any reason why this lint shouldn't be enabled. The only problem is that the lint suggests moving the significant drop above the `while let`, which is clearly invalid in the case of `while let`. I don't know if this is fixable, but this PR simply disables the wrong suggestions.
For `if let`, it seems that another lint called `if_let_mutex` has some overlapping functionality. But `significant_drop_in_scrutinee` is a bit stricter, as it will trigger even if the `else` branch does not try to lock the same mutex.

Reduce the size of lintcheck JSON output
Saves about 80% of the size by picking out what we need rather than serialising the whole diagnostic
