Tweak the timer task cost estimation based on user data
We pulled 1000 deep report traces and computed a histogramme of the
timer task duration. Just like loading thasks, the vast majority of
timer are fast. The threshold we care (most) about is 50ms which
turns out to be the 98.78th percentile of the timer task durations.
We mirror the task cost estimation settings used for loading tasks
for the timers since the distribution is very similar.
