ServiceWorker: Introduce ServiceWorkerRegistrationObjectInfo for cleanup

ServiceWorker: Introduce ServiceWorkerRegistrationObjectInfo for cleanup

This change introduces ServiceWorkerRegistrationObjectInfo which carries
'handle_id' and 'scope' for ServiceWorkerRegistration object in the renderer
side over the IPC message, and removes unnecessary reference counting for
ServiceWorker object on the registration sequence.
