This PR extends trait_duplication_in_bounds to cover trait objects.

Currently,

fn foo(_a: &(dyn Any + Send + Send)) {}

generates no warnings. With this PR, it will complain about a duplicate trait and can remove it

Moved from rust-lang/rust#110991

changelog: [trait_duplication_in_bounds]: warn on duplicate trait object constraints
