Alter signatures on PayloadFactory class

[fractalwrench]

Goal

Alters the PayloadFactory interface so that callers don't need to know whether a session/background activity is being constructed. This is done by passing the process state, and having the implementation call the appropriate function. This refactor will make it easier to switch over to using the new payload.

Testing

Relied on existing unit test coverage for the session orchestrator.
