Introduce Signin.NumberOfActiveAccounts.* metrics
They come in .Last7Days and .Last28Days variants, and are somewhat
modeled after the existing Profile.NumberOfActiveProfiles histogram.
They track the number of accounts that were "active", i.e. were used as
the primary account in any profile, over the last 7 or 28 days.
They're implemented in a new class ActiveAccountsTracker, which
maintains a dict of <gaia_id_hash, last_active_time> in LocalState and
periodically (once every 24h) records the histograms.
An account is marked as active at profile load and at signin (by
SigninMetricsService), and when a corresponding browser/window becomes
active (by ProfileManager, or BrowserStateActivitySceneAgent on iOS -
similar to how the existing Profile.NumberOf*Profiles metrics are
handled).
