Kaushik Iska ca5cc907a9 [tracing] SceneDisplayLag is a synchronous event (flutter/engine#17878)
This change converts it from an events that spans a time interval
to an event that occurs at an instant.

We also emit this trace event when there is no lag as opposed to
only when there was a lag to make it monotonous.
