Add sync marker traces to allow fast parsing

Periodically writes a fixed 128 bits sync marker to traces,
every 10s, together with the clock snapshots. This is to
allow concurrent offline processing of traces, by being able to
quickly seek the markers and partitioning the trace.

Test: perfetto_unittests --gtest_filter=*ResynchronizeTraceStreamUsingSyncMarker
