service worker: Use mojofied ServiceWorkerStorage::UpdateToActiveState()

This CL increases the android binary sizes by ~30kb. Most of the
increase (~29kb) comes from mojo generated code and there isn't much we
can do to reduce them. Introducing the mojo interface is necessary for
migrating ServiceWorkerStorage to the storage service. See the design
doc [1] for the motivation of the migration and plans.
