Add tracepoints to dumpstate sections
This change adds async tracepoints to DurationReporter so that section
durations can be captured in traces. Showmap sections are omitted to
avoid spamming the trace viewer.
Test: Manually took a trace during a bug report to verify that bug
report sections were captured.
