Decouple ProcessStateRecord from ProcessRecord

Introduce interfaces to decouple ProcessStateRecord from direct
dependencies on ProcessRecord and ActivityManagerService.
- ProcessRecord now implements ProcessStateRecord.StatePuller
  to provide necessary info for OOM adjustment calculations.
- ProcessProfileRecord implements
  ProcessStateRecord.StartedServiceObserver
  to react to changes in component-related states (activities, services,
  broadcasts) and update hosting component types accordingly.
