FormatArgsExpn: Find comma spans and ignore weird proc macro spans
Fixes the following cases:
A missing `, 1` from the `expect_fun_call` suggestion:
```rust
Some(()).expect(&format!("{x} {}", 1));
```
```
warning: use of `expect` followed by a function call
--> t.rs:7:14
|
7 | Some(()).expect(&format!("{x} {}", 1));
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: try this: `unwrap_or_else(|| panic!("{x} {}"))`
```
The suggestion removing from the comma in the comment rather than the one after the format string:
```rust
println!(
"{}",
// a comment, with a comma in it
x
);
```
```
warning: variables can be used directly in the `format!` string
--> t.rs:9:5
|
9 | / println!(
10 | | "{}",
11 | | // a comment, with a comma in it
12 | | x
13 | | );
| |_____^
|
help: change this to
|
10 ~ "{x}",
11 ~ // a comment
|
```
It also no longer accepts expansions where a format string or argument has a "weird" proc macro span, that is one where the literal/expression it outputs has the span of one of its inputs. Kind of like a `format_args` specific `clippy_utils::is_from_proc_macro`, e.g. `format!(indoc! {" ... "})`

Add `disallowed_macros` lint
Closes#7790Fixes#9558
`clippy_utils::def_path_res` already resolved macro definitions which is nice, it just needed a tweak to be able to disambiguate e.g. `std::vec` the module & `std::vec` the macro, and `serde::Serialize` the trait & `serde::Serialize` the derive macro

[arithmetic-side-effects] Do not ignore literal references
To my utter surprise, `rustc` does does not warn stuff like `let n: u8 = &255 + &1` or `let n: u8 = 255 + &1`.

fallout: fix tests to allow uninlined_format_args
In order to switch `clippy::uninlined_format_args` from pedantic to style, all existing tests must not raise a warning. I did not want to change the actual tests, so this is a relatively minor change that:
* add `#![allow(clippy::uninlined_format_args)]` where needed
* normalizes all allow/deny/warn attributes
* all allow attributes are grouped together
* sorted alphabetically
* the `clippy::*` attributes are listed separate from the other ones.
* deny and warn attributes are listed before the allowed ones

new `implicit_saturating_add` lint
This fixes#9393
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
- \[x] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`

Fix#9579
changelog: [`upper_case_acronyms`]: check the enum name
Replace `expr_visitor` with `for_each_expr`
This is a minor change which uses `ControlFlow` rather than a boolean. This also runs the visitor rather than returning the visitor, which results in a small readability win as well.

Fix and improve `match_type_on_diagnostic_item`
This extracts the fix for the lint out of #7647. There's still a couple of other functions to check, but at least this will get lint working again.
The two added util functions (`is_diagnostic_item` and `is_lang_item`) are needed to handle `DefId` for unit and tuple struct/variant constructors. The `rustc_diagnostic_item` and `lang` attributes are attached to the struct/variant `DefId`, but most of the time they are used through their constructors which have a different `DefId`. The two utility functions will check if the `DefId` is for a constructor and switch to the associated struct/variant `DefId`.
There does seem to be a bug on rustc's side where constructor `DefId`s from external crates seem to be returning `DefKind::Variant` instead of `DefKind::Ctor()`. There's a workaround put in right.

changelog: none
* Check for `const`s and `static`s from external crates
* Check for `LangItem`s
* Handle inherent functions which have the same name as a field
* Also check the following functions:
* `match_trait_method`
* `match_def_path`
* `is_expr_path_def_path`
* `is_qpath_def_path`
* Handle checking for a constructor to a diagnostic item or `LangItem`
