This PR updates the `from_raw_with_void_ptr` lint, which covered `Box::from_raw`, to also cover the `from_raw` static method of the `Rc`, `Arc`, `alloc::rc::Weak` and `alloc::sync::Weak` types. It also improves the description and error messages of this lint. --- changelog: [`from_raw_with_void_ptr`]: Now works with the `Rc`, `Arc`, `alloc::rc::Weak` and `alloc::sync::Weak` types.
