Path to a definition, optionally "fully-qualified" with a Self type, if the path points to an associated item in a trait.

E.g. an unqualified path like Clone::clone has None for Self, while <Vec<T> as Clone>::clone has Some(Vec<T>) for Self, even though they both have the same two-segment Clone::clone Path.

Type-related paths, e.g. <T>::default or <T>::Output. Will be resolved by type-checking to an associated item.

UFCS source paths can desugar into this, with Vec::new turning into <Vec>::new, and T::X::Y::method into <<<T>::X>::Y>::method, the X and Y nodes each being a TyPath(QPath::TypeRelative(..)).
