[DFMs] Measure DFM install duration

We track two durations:
- Install duration for module requested first since the last Chrome
  start. Those installs are unlikely to come from cache and the install
  duration should therefore be most representative.
- Install duration for module requested before Chrome started last. May
  be very short due to caching. Included here for completeness.
