Add question-mark-used lint
This lint complains when the question mark operator (try operator) is used. This is a restriction lint that can be useful on local scopes where a custom error handling macro is supposed to be used to augment the error based on local scope data before returning.

Add `let_underscore_untyped`
Fixes#6842
This adds a new pedantic `let_underscore_untyped` lint which checks for `let _ = <expr>`, and suggests to either provide a type annotation, or to remove the `let` keyword. That way the author is forced to specify the type they intended to ignore, and thus get forced to re-visit the decision should the type of `<expr>` change. Alternatively, they can drop the `let` keyword to truly just ignore the value no matter what.

[significant_drop_tightening] Add MVP

Creates the lint with minimum functionalities, which is a good start IMO.

Use `target` instead of `machine` for mir interpreter integer handling.
The naming of `machine` only makes sense from a mir interpreter internals perspective, but outside users talk about the `target` platform. As per https://github.com/rust-lang/rust/pull/108029#issuecomment-1429791015
r? `@RalfJung`
As this is a lint about "style", and a purely cosmetical choice (using `<A: Trait>` over `impl Trait`), a lot of other files needed to be allowed this lint.
Avoid accessing HIR when it can be avoided
Experiment to see if it helps some incremental cases.
Will be rebased once https://github.com/rust-lang/rust/pull/107942 gets merged.

Fix false positives for `extra_unused_type_parameters`
Don't lint external macros. Also, if the function body is empty, any type parameters with bounds on them are not linted. Note that only the body needs be empty - this rule still applies if the function takes any arguments.

It is not sufficient to ignore break from a block inside the loop.
Instructions after the break must be ignored, as they are unreachable.
This is also true for all instructions in outer blocks and loops
until the right block is reached.
This lint complains when the question mark operator (try operator)
is used. This is a restriction lint that can be useful on local
scopes where a custom error handling macro is supposed to be used
to augment the error based on local scope data before returning.
Introduce `-Zterminal-urls` to use OSC8 for error codes
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.
