Use ordered sets for shape id sequences#2742

Several shapes have properties that are sequences of shape ids, such as an OperationShape's errors. Previously these shapes were using the List structure to store these in Java, but since the order of these sequences isn't actually semantically important, it was causing equality checks to fail where the should not. This replaces those usages of `List` to `LinkedHashSet`. That way the order in the model may still be preserved, but the equality is set equality. Additionally, duplicates in these sequences have no meaning, so the deduplication of sets is a benefit in that sense too.

Note that we already use ordered sets for the lists of operations and resources on service and resource shapes
