This variant was only used for service workers' openWindow method, which has been changed to no longer behave in this way, meaning that the type can be removed. The follow-up simplification of removing 'ContentChild::ProvideWindowCommon', and moving the logic directly into 'BrowserChild' is not done in this bug, and will be done in a follow-up instead.
