Following Bug 247926, we expose 'stable' features to the Safari 'Develop' menu to support A/B testing by developers so they can isolate the cause of page regression to specific features. This has created an overly-cumbersome UI, and surfaced features that cannot be disabled on the modern web (and which have been shipping for many years). This patch updates our Feature flag definitions to use 'shipping' for long-shipping features. These will no longer be displayed in the UI, and the feature toggles will likely be removed in a future update as they are no longer conditional, but are foundational to the modern web.
