Add regression test for `string_lit_as_bytes` issue

Closes #5619

Before the fix in https://github.com/rust-lang/rust/pull/72637, `string_lit_as_bytes` was incorrectly triggering on the `env!` macro. With the fix merged, this test makes sure that the lint is not triggering anymore.

New lint: iter_next_slice

Hello, this is a work-in-progress PR for issue: https://github.com/rust-lang/rust-clippy/issues/5572

I have implemented lint to replace `iter().next()` for `slice[index..]` and `array` with `get(index)` and `get(0)` respectively. However since I made a lot of changes, I would like to request some feedback before continuing so that I could fix mistakes.

Thank you!

Rollup merge of #5656 - ebroto:len_zero_ranges, r=matthiaskrgr
len_zero: skip ranges if feature `range_is_empty` is not enabled

If the feature is not enabled, calling `is_empty()` on a range is ambiguous. Moreover, the two possible resolutions are unstable methods, one inherent to the range and the other being part of the `ExactSizeIterator` trait.

Since `len_zero` only checks for existing `is_empty()` inherent methods, we only take into account the `range_is_empty` feature.

Make empty_line_after_outer_attr an early lint

Fixes #5567

Unfortunately I couldn't find a way to reproduce the issue without syn/quote. Considering that most real-world macros use syn and/or quote, I think it's okay to pull them in anyway.

ptr_arg: honor `allow` attribute on arguments

The `intravisit::Visitor` impl for `LateContextAndPass` only takes into account the attributes of a function parameter inside the `check_param` method. `ptr_arg` starts its heuristics at `check_item` / `check_impl_item` / `check_trait_item`, so the `allow` is not taken into account automatically.

new_without_default: do not suggest deriving

---

changelog: do not suggest deriving `Default` in `new_without_default`

This commit changes the behavior of the `new_without_default` lint to not suggest deriving `Default`. This suggestion is misleading if the `new` implementation does something different than what a derived `Default` implementation would do, because then the two methods would not be equivalent.

Instead, the `can_derive_default` check is removed, and we always suggest implementing `Default` in terms of `new()`.
