Add more granularity to the Browser.Tabs.TotalSwitchDuration metrics

The new metrics will indicate the state of the tab Chrome is switching
to (loaded/frozen) and will give more information about the impact of
tab freezing on tab switch time.

All the functions that takes a |tab_switch_start_time| argument have
been updated to accept a newly defined TabSwitchStartState structure
instead, this allows passing more information about the tab switch
event to the TabSwitchTimeRecorder class.
