perf cs-etm: Introduce the concept of trace ID queues
In an ideal world there is one CPU per cs_etm_queue and as such, one
trace ID per cs_etm_queue. In the real world CoreSight topologies allow
multiple CPUs to use the same sink, which translates to multiple trace
IDs per cs_etm_queue.
To deal with this a new cs_etm_traceid_queue structure is introduced to
enclose all the information related to a single trace ID, allowing a
cs_etm_queue to handle traces generated by any number of CPUs.
