perf cs-etm: Add support for multiple traceID queues
When operating in CPU-wide trace mode with a source/sink topology of N:1
packets with multiple traceID will end up in the same cs_etm_queue. In
order to properly decode packets they need to be split in different
queues, i.e one queue per traceID.
As such add support for multiple traceID per cs_etm_queue by adding a
new cs_etm_traceid_queue every time a new traceID is discovered in the
trace stream.
