Remove `#![allow(unused)]` and `--crate-name` from `cargo dev new_lint` generated tests
changelog: none
Also removes some unused flags from `ui-cargo` tests because the entrypoint is now the `Cargo.toml`, not the `.rs` files
New lint [`iter_skip_zero`]
Idea came from my contribution to `unnecessary_cast` recently. Sorry about that 😅
Could be an issue if somebody manually implements `skip`, but I don't think anybody will (and this would be an issue with other lints too, afaik)
changelog: New lint [`iter_skip_zero`]
New lint [`string_lit_chars_any`]
Closes#10389
This lint can probably be deprecated if/when rustc optimizes `.chars().any(...)`.

Rewrite [`tuple_array_conversions`]
Fixes#11100Fixes#11144Fixes#11124#11082 still needs discussion and #11085 likely can't be fixed.
changelog: [`tuple_array_conversions`]: Move to `pedantic`
changelog: [`tuple_array_conversions`]: Don't lint if mutability of references changes
changelog: [`tuple_array_conversions`]: Don't lint if bindings don't come from the exact same pattern
changelog: [`tuple_array_conversions`]: Don't lint if bindings are used for more than just the conversion
new lint: `format_collect`
A perf lint that looks for `format!`ing inside of `map`, then collecting it into a `String`. Did a quick benchmark locally and it's a bit more than 2x faster with fold.
`write!` is still not optimal (presumably because the fmt stuff goes through dynamic dispatch), but it's still a lot better than creating a new string on every element.
I thought about making a machine applicable suggestion, but there's a lot of suggestions that need to be made here, so I decided to just add help messages.

don't hide lifetimes for `LateContext`
Running `cargo dev new_lint --type methods` creates the lint file with hidden lifetimes for the `LateContext` parameter (i.e. `&LateContext`, when it should be `&LateContext<'_>`). This is already warned on with `#![warn(rust_2018_idioms)]`, so clippy should not use hidden lifetimes

Trigger a rebuild when `CLIPPY_CONF_DIR` changes
changelog: none
This is a fix for https://github.com/rust-lang/rust-clippy/issues/9928#issuecomment-1634698183, any time `CLIPPY_CONF_DIR` changes cargo will now rebuild the crate clippy is being run on, giving it a chance to lint with the (potentially) different config file
