Deprecation of GCM-based Web Push Subscriptions

Chrome introduced Web Push Notifications in M42, based on proprietary GCM authentication that requires people to create a Google Cloud Project ID. A year later, in M52, we improved this by launching support for VAPID, a mechanism that continues to striclty associate messages with a particular sender, but no longer relies on proprietary mechanisms for obtaining that identifier. We intent to only support VAPID going forward.
