Reduce indexing boilerplate for serializable/transferrable objects. (#36624)
Rather than creating unique types for each pipeline-namespaced index type (eg. MessagePortId, DomExceptionId, etc.), we can create a generic common type that uses a marker to prevent type confusion. This change allows us to reduce the boilerplate code required when implementing serializable/transferable interfaces, since the structured clone implementation can rely on the common type. Testing: Existing WPT tests for serialization and transferring provide coverage. --------- Signed-off-by: Josh Matthews <josh@joshmatthews.net>
