why some structure from net/ has its param traits defined in cc/?

NetworkTrafficAnnotation describes a network request and is transferred to each
network request function.
As it needs to be added to a .mojom file, I have defined it here.
Do you suggest I create a net_param_treits and move these lines there, or
totally object this approach?
