Refactor Worker and ThreadSafeState (#3242)

* Split ThreadSafeState into State and GlobalState. State is a "local"
  state belonging to "Worker" while "GlobalState" is state shared by
  whole program.
* Update "Worker" and ops to use "GlobalState" where applicable
* Move and refactor "WorkerChannels" resource
