This PR adds the lint explicit_deref_method that suggests replacing deref() and deref_mut() with &*a and &mut *a.

It doesn't lint inside macros.

This PR is the continuation of #3258.

changelog: Add lint explicit_deref_method.

Fixes: #1566

Sorry for taking so long for the review. I don't have an excuse, just wasn't really motivated to review PRs recently.

It's totally fine not to instant review PRs 😉
plus you updated Clippy so we don't have to constantly update lints count/array size to keep the PR mergeable 👍
