  [iOS] Prewarmed web process is not launched as an extension

Reviewed by Per Arne Vollan.

If a prewarmed WebContent process is created before the first WebPage is created, the process would
not be launched using ExtensionKit even if ManageWebKitProcessesAsExtensions is enabled.

Fixed this by moving the call to AuxiliaryProcessProxy::setManageProcessesAsExtensions from
WebProcessPool::createWebPage to WebProcessPool::createNewWebProcess so that the global flag is set
before the prewarmed WebContent process is created. Since pagePreferences are not available at this
point, also reverted to a user default for using ExtensionKit rather than a web preference.
