fix(scheduler): release replay-event payloads after the simulator pushes them (bug-1884, part 2)

Browse source 
sim_process_replay_event_message() now hands the decoded replay event to
the caller, which keeps it beside the translated core event and frees it
after xce_core_push_events() with driver.c's release_translated_payload()
rules: a pushed config is kept by the core, and a rusages report is kept
by the job it found. An untranslatable event is freed at once, and events
after the last session are freed at the end. The payloads were an
"accepted leak" per event; exit-time leak on the reproduction replay
75,495 -> 25,807 bytes.
