telemetry: Compute multiple first gesture scroll updates if there were multiple gestures

If the story performed multiple gesture interactions, compute multiple
corresponding values for the first_gesture_scroll_update_latency metric.
Doing multiple gestures instead just one helps reduce noise in that
metric.
