This PR also updates several audits that were still using the TTI graph or entire PDG to compute overallSavingsMs. Now those audits will just use their LCP savings to fill out overallSavingsMs instead.
Also, turns out we were still using overallSavingsMs in the flow report to sort audits in the summary page tooltip. Would be nice to use the same sort order as the performance category but that isn't a super high priority. This PR just does a simple sort by score then sort by LCP savings.
