2025-03-24gccrs: support generic super traits recursivelyPhilip Herron10-60/+166
In order to handle generic super traits on any trait bound we need to ensure we track the TypeBoundPredicate as part of the TraitReference instead of just the raw TraitReferences because these will have any applied generics enplace. Then for any TypeBoundPredicate it takes a copy of the super traits because this is the usage of a TraitBound and we can apply generics which then need to be recursively applied up the chain of super predicates. The main tweak is around TypeBoundPredicate::lookup_associated_item because we need to associate the predicate with the item we are looking up so the caller can respect the generics correctly as well.
