[tab_under] Simplify visibility metrics and add a new one We used to have two visibility trackers, one for the tab in general, and one for tabs after they did a tab-under. This doesn't actually make a whole lot of sense, as one of the trackers is just a subset of the other one! This patch removes the tab-under visibility tracker in favor of just logging a TimeDelta instead. We also add a new metrics for visibility time *before* the first tab-under, for tabs that do tab-unders.
