Fix cargo dev fmt
Adds more details about how a significant drop in a match scrutinee can
cause a deadlock and include link to documentation. Emits messages
indicating temporaries with significant drops in arms of matches and
message about possible deadlocks/unexpected behavior.
changelog: Add more details to significant drop lint to explicitly show
how temporaries in match scrutinees can cause deadlocks/unexpected
behavior.
feat(lint): add default_iter_empty

Make `ExprKind::Closure` a struct variant.
Simple refactor since we both need it to introduce additional fields in `ExprKind::Closure`.

Rework `branches_sharing_code`
fixes#7378
This changes the lint from checking pairs of blocks, to checking all the blocks at the same time. As such there's almost none of the original code left.
changelog: Don't lint `branches_sharing_code` when using different binding names
And likewise for the `Const::val` method.
Because its type is called `ConstKind`. Also `val` is a confusing name
because `ConstKind` is an enum with seven variants, one of which is
called `Value`. Also, this gives consistency with `TyS` and `PredicateS`
which have `kind` fields.
The commit also renames a few `Const` variables from `val` to `c`, to
avoid confusion with the `ConstKind::Value` variant.
Fix some `#[expect]` lint interaction
Fixing the first few lints that aren't caught by `#[expect]`. The root cause of these examples was, that the lint was emitted at the wrong location.

Improve lint doc consistency
changelog: none
This is a continuation of #8908.
Notable changes:
- Removed empty `Known Problems` sections
- Removed "Good"/"Bad" language (replaced with "Use instead")
- Removed (and added some 😄) duplication
- Ignored the [`create_dir`] example so it doesn't create `clippy_lints/foo` 😄
