Auto merge of #10184 - robertbastian:master, r=xFrednet 

Allow implementing `Hash` with derived `PartialEq` (`derive_hash_xor_eq`

This is a common pattern and is totally allowed by the `Hash` trait.

Fixes #2627

changelog: Move: Renamed `derive_hash_xor_eq` to [`derived_hash_with_manual_eq`]
[#10184](https://github.com/rust-lang/rust-clippy/pull/10184)
changelog: Enhancement: [`derived_hash_with_manual_eq`]: Now allows `#[derive(PartialEq)]` with custom `Hash` implementations
