sim: trace: centralize the system tracing

First we convert the ETRACE_P to STRACE_EVENTS_P.  This means we move from
using the sim_events.trace storage to the common sim_state_base.trace_data
array.  With that deleted, the common trace init code can be simplified so
the sim state works the same as the sim cpu.
