gl: Add TraceEvents for eglGetFrameTimestamps.
Sorts the events by timestamp and records:
1) A trace event for the entire range.
2) Nested ranges within (1) of the remaining events, which provide
a nice visual representation of a frames events and durations,
making anomalous frames very apparent.
3) Nested instant events within (1) for a more detailed description
of the event.
Bug: 769415
Test: Traces look niice.
