Andreas Farre 8f3777c8b5 Bug 1618236 - Make CollectPerformanceInfo use BrowsingContextGroup to find DocGroups. r=tarek,peterv
By having CollectPerformanceInfo traverse the BrowsingContextGroup and
tree of BrowsingContexts we can hide the task of getting the DocGroups
befind an API in BrowsingContextGroup and ease the removal of
TabGroups.
