trace: remove global 'uint16 dstate[]' array
Instead of having a global dstate array, declare a single 'uint16 TRACE_${EVENT_NAME}_DSTATE' variable for each trace event. Record a pointer to this variable in the TraceEvent struct too. By turning trace_event_get_state_dynamic_by_id into a macro, this still hits the fast path, and cache affinity is ensured by declaring all the uint16 vars adjacent to each other.
