Reviewed by Patrick Angle and Elliott Williams.

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.

This also corrects MediaSourceEnabled and SafeBrowsing to be 'embedder'.

* Source/WTF/Scripts/GeneratePreferences.rb: Add 'shipping' as a recognized status.
