[Invalidations] Add GetInvalidatorState() to Invalidator{,Frontend}

Combine OnNotifications{Enabled,Disabled}() into OnInvalidatorStateChange().  Replace NotificationsDisabledReason with InvalidatorState.

Rename OnIncomingNotification to OnIncomingInvalidation.  Also change
some references of "notification" to "invalidation".

Set the initial invalidator state in ChromeToMobileService.  Also remove OnNotificationsEnabled() call from OnIncomingInvalidation().

Instantiate InvalidatorTest template for ProfileSyncService.

Move comments for invalidation-related functions from ProfileSyncService to InvalidatorFrontend.

Put DISALLOW_COPY_AND_ASSIGN on some classes.

Fix comment in invalidator.h.
