startop: Add timestamps for IntentStarted and ActivityLaunchFinished.

The timestamps are used to compute duration of TotalTime and ReportFullyDrawn.

TotalTime = t(ActivityLaunchFinished) - t(IntentStarted)
ReportFullyDrawn = t(ReportFullyDrawn) - t(IntentStarted)

where t(x) is the timestamp of x.
