Update all site scores to use Lighthouse 3.0 metrics

@kristoferbaxter Thanks so much for getting this kickstarted off this weekend 🎉

Sounds good, once those issues capturing TTI are resolved I'll be happy to rerun tests for all the implementations and use the First Interactive times. We can then decide to use consistentlyInteractive once we feel it's smoothed out 💃

Opening up discussion on this again 💬

@addyosmani how do you feel about the consistentlyInteractive metrics with the current LH version (2.3.0)? My experiences with it have usually shown it to match the firstInteractive numbers, but wanted to check in too see if it has smoothed out to a point we can start shifting to it 🙌

As discussed, we'll be holding off adding this for a few more days until WPT lands LH 3.0 🚀
