b5ef084e - Define scope to job queue map struct (#1183)

Define scope to job queue map struct (#1183) This change clarifies a job queue isn't owned by a service worker registration and reflects the implementations more precisely by defining the scope to job queue map struct. This also makes it use the queue struct defined in Infra instead of the FIFO queue concept that didn't have a concrete reference. Fixes #1180.
