Bump ui_test to 0.23
Notable changes: more control over run/rustfix/... and other rustc-specific features. All of these can in theory now be implemented entirely out of tree

Changelog for Clippy 1.78 🪄
Roses and Violets have colors,
Red and Blue are the two,
I'm getting to the end of my masters,
what a cool goal to pursue

fix suggestion error for [`manual_is_ascii_check`] with missing type
fixes: #11324fixes: #11776
changelog: improve [`manual_is_ascii_check`] to suggest labeling type in closure, fix FP with type generics, and improve linting on ref expressions.
Modify lint pass note for consistency with the book
This PR:
- removes the note which appears when an early lint pass is created using `cargo dev new_lint`.
- adds a note that encourages contributors to use an early pass unless type information is needed if a late lint pass is created using `cargo dev new_lint`.
Late pass remains the default value if no pass is specified as most lints use late pass.
Closes#12595

Add StaticForeignItem and use it on ForeignItemKind
This is in preparation for unsafe extern blocks that adds a safe variant for functions inside extern blocks.

suppress `readonly_write_lock` for underscore-prefixed bindings
Fixes#12733
Unsure if there's a better way to prevent this kind of false positive but this is the one that made most sense to me.
In my experience, prefixing bindings with an underscore is the usual way to name variables that aren't used and that exist purely for executing drop code at the end of the scope.

[`type_complexity`]: Fix duplicate errors
Relates to #12379
Following message was duplicated:
```
LL | fn def_method(&self, p: Vec<Vec<Box<(u32, u32, u32, u32)>>>) {}
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= note: duplicate diagnostic emitted due to `-Z deduplicate-diagnostics=no`
error: very complex type used. Consider factoring parts into `type` definitions
--> tests/ui/type_complexity.rs:55:15
```
Methods `check_trait_item` and `check_fn` were both checking method named def_method.
Now `check_trait_item` only checks methods without body.

clippy::single_match(_else) may be machine applicable
```
changelog: [`single_match`]: make the lint machine-applicable
changelog: [`single_match_else`]: make the lint machine-applicable

The lint doesn't use placeholders. I've tried it on my codebases, and all instances of it applied without problems.
check if closure as method arg has read access in [`collection_is_never_read`]
fixes: #11783

changelog: fix [`collection_is_never_read`] misfires when use `retain` for iteration
configurably allow `useless_vec` in tests
This adds a `àllow-useless-vec-in-test` configuration which, when set to `true` will allow the `useless_vec` lint in `#[test]` functions and code within `#[cfg(test)]`. It also moves a `is_in_test` helper to `clippy_utils`.

Fix false positive in `cast_possible_truncation`
Fixes [#12721](https://github.com/rust-lang/rust-clippy/issues/12721)
changelog: [`cast_possible_truncation`]: Separated checking whether integer constant has sufficient leading zeroes to be safely casted when getting remainder from bitwise and, since the latter allows a constant on either side of the operator to increase the number of leading zeroes that can be guaranteed.
fix [`large_stack_arrays`] linting in `vec` macro
fixes: #12586
this PR also adds a wrapper function `matching_root_macro_call` to `clippy_utils::macros`, considering how often that same pattern appears in the codebase.
(I'm always very indecisive towards naming, so, if anyone have better idea of how that function should be named, feel free to suggest it)
