This pref should only be used by ExtensionManagement, so it should be registered
by ExtensionManagementFactory::RegisterProfilePrefs.

See RegisterProfilePrefs in
components/keyed_service/content/browser_context_keyed_base_factory.h. It's a
virtual method of factories that can be used to register preferences. See
chrome/browser/policy/cloud/user_policy_signin_service_factory.h for an example.
