Adds CORS-specific headers to every response in the API.

<p>Values will be provided for the headers added to each operation by updating
the API Gateway integration of each operation to provide a static value for
each CORS header. This mapping is performed in {@link AddIntegrations}.

<p>This extension only takes effect if the service being converted to
OpenAPI has the CORS trait.
