BUG=708901
Original issue's description:
> Pref service: add support for tracked prefs.
>
> This:
> - Adds TrackedPersistentPrefStoreConfiguration: a mojo struct containing
> the necessary state for constructing a PrefStore identical to the one
> constructed in ProfilePrefStoreManager::CreateProfilePrefStore().
> - Moves the enums used to configure tracked prefs into the mojom.
> - Extracts the creation of tracked pref store from
> ProfilePrefStoreManager::CreateProfilePrefStore() into
> prefs::CreateTrackedPersistentPrefStore().
> - Changes prefs::CreatePersistentPrefStore() so an appropriate
> configuration results in prefs::CreateTrackedPersistentPrefStore()
> being called to create the backing PrefStore.
