`missing_trait_methods` shouldn't consider hidden methods

[c410-f3r]

There are some hidden built-in methods not intended for public usage.

#![deny(clippy::missing_trait_methods)]

struct Foo;

impl Eq for Foo {}

impl PartialEq for Foo {
  fn eq(&self, _: &Self) -> bool {
    true
  }
}

error: missing trait method provided by default: `assert_receiver_is_total_eq`
 --> src/lib.rs:5:1
  |
5 | impl Eq for Foo {}
  | ^^^^^^^^^^^^^^^
