This commit validates and standardizes the behavior that has existed for
many years in AWS SDKs: requiring that shapes in the closure of a
service are case-insensitively unique regardless of their namespaces
(with some exceptions for simple types and lists/sets). This change
ensures that SDK code gen does not need to persist the namespaces in
their generated code, and that they can create their own
namespaced/siloed copies of shapes for each service (removing the need
to publish and pull in dependencies on shared types).
