Disable "if_not_else" lints from firing on else-ifs
Fixes#7892
1. Convert `['if_not_else']` to `LateLintPass` and use `clippy_utils::is_else_clause` for checking.
2. Update tests.
changelog: [`if_not_else`] now ignores else if statements.

Ignore references to type aliases in ptr_arg
Works using the fact that the hir path will point to a TyAlias, rather than being resolved to the underlying type
Fixes#7699
changelog: [`ptr_arg`] No longer lints references to type aliases
Add unit-hash lint
changelog: [`unit_hash`] Add lint for hashing unit values
This will lint for situations where the end user is attempting to hash a unit value (`()`), as the implementation in `std` simply [does nothing][impl]. Closes#7159 .
Example:
```rust
().hash(&mut state);
// Should (probably) be replaced with:
0_u8.hash(&mut state);
```
[impl]: a5f164faad/library/core/src/hash/mod.rs (L656)
Register the generated lints from `cargo dev new_lint`
How to register a lint was something that took me a couple reads to figure out, this will hopefully make that easier. It appends the created lint to the end of the list when running `cargo dev new_lint`

Fix `question_mark` FP on custom error type
Closes#7859#7840 aims to ignore `question_mark` when the return type is custom, which is [covered here](df65291edd/tests/ui/question_mark.rs (L144-L149)). But this fails when there is a call in conditional predicate
changelog: [`question_mark`] Fix false positive when there is call in conditional predicate
Clean up tests/ui/rename.rs
Part one of #7057, cleaning up `tests/ui/rename.rs`. `tests/ui/deprecated.rs` will be updated in a subsequent PR.

new lint: string-slice
This is a restriction lint to highlight code that should have tests containing non-ascii characters. See #6623.
changelog: new lint: [`string-slice`]
Fix `match_str_case_mismatch` on uncased chars
False positives would result because `char::is_lowercase` and friends will return `false` for non-alphabetic chars and alphabetic chars lacking case (such as CJK scripts). Care also has to be taken for handling titlecase characters (`Dz`) and lowercased chars with no uppercase equivalent (`ʁ`).
For example, when verifying lowercase:
* Check `!any(char::is_ascii_uppercase)` instead of `all(char::is_ascii_lowercase)` for ASCII.
* Check that `all(|c| c.to_lowercase() == c)` instead of `all(char::is_lowercase)` for non-ASCII
Fixes#7863.

Update `str` utils to prevent ICEs and FNs
This PR reworks some string handling for lints regarding enum naming. I hope the refactoring will prevent future ICEs and help with new bug free implementations.
It might be better to review this PR by going through the commits, as `clippy_utils::camel_case` was renamed to `clippy_utils::str_utils` and then changed further. GH sadly doesn't really make the changes that obvious 🙃
Not too much more to say. Have a nice day 🌞

r? `@flip1995` - thanks again for your assistance in zulip earlier, figured I'd take a pass at incorporating your recommendation to delete or use a new branch into the excellent docs here
