Move trace event emitting calls to outside of test run time measurement

Move trace event emitting calls to outside of test run time measurement

This removes the overhead of emitting trace events from run time 
measurement.
On tests like Layout/character_fallback_aat.html, this reduces the 
test's duration 3x (0.015ms --> 0.005ms)
