lintcheck: fix clap panic
clap 4.1.4 panics if `-` is used at the start of an argument:
```
$ cargo lintcheck
[…]
thread 'main' panicked at 'Argument recursive: long "--recursive" must not start with a `-`, that will be handled by the parser', /home/sam/.cargo/registry/src/github.com-1ecc6299db9ec823/clap-4.1.4/src/builder/debug_asserts.rs:82:13
```

It is possible to use conditional compilation to prevent Clippy from
evaluating certain code. This adds a brief explanation of how to use the
feature with conditional compilation, and mentions that generally it’s
preferable to use something like `#[allow(clippy::all)]`.
Fixes#10220 — Ability to skip files or blocks entirely
Implement `deferred_projection_equality` for erica solver
Somewhat of a revival of #96912. When relating projections now emit an `AliasEq` obligation instead of attempting to determine equality of projections that may not be as normalized as possible (i.e. because of lazy norm, or just containing inference variables that prevent us from resolving an impl). Only do this when the new solver is enabled
Clap was updated in rust-lang/rust-clippy#10270, which broke the command
line of clippy_dev. This swaps out contains_id, which now returns always
true in the places it was used with get_flag.
Terminals supporting the OSC8 Hyperlink Extension can support inline
anchors where the text is user defineable but clicking on it opens a
browser to a specified URLs, just like `<a href="URL">` does in HTML.

Make `[clippy::dump]` support trait items
Roses are red,
violets are blue,
trait items are rare,
`[clippy::dump]` is too
---
Let's just ignore the horrible poem... anyways. While working on Marker I noticed, that `[clippy::dump]` doesn't work on trait item (See [Playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=e2d9791ffa2872e7c09a9dfbd470350c)). This simply adds support for that. `[clippy::dump]` doesn't have UI tests, to make it more resistant to changes in the AST. I tested it locally and the dump works after these changes.

Add `extra_unused_type_parameters` lint
Closes#9240. ~~Keeping this as draft for now, because of a bug that I don't know how to fix.~~ It seems that opaque return types are not walked properly, for some unknown reason. As in, the following:
```rust
fn used_ret_opaque<A>() -> impl Iterator<Item = A> {
std::iter::empty()
}
```
This triggers the lint even though it shouldn't. Discussion on Zulip didn't illuminate any possible reasons why, so PR-ing this now to increase visibility.
