IPC currently needs each distinct numeric wrapper to provide its own serialization specialization. That makes compositor resource ids and pixel-unit wrappers grow one-off glue as soon as they cross an endpoint. Teach LibIPC to serialize AK::DistinctNumeric wrappers through their underlying value type and remove the redundant Web-side specializations for UniqueNodeID and DevicePixels. Existing compound pixel-unit serializers now rely on generic wrapper support for their components. This is preparatory work required to add IPC between the main and compositor threads.
