Create a new ephemeral #WebKitWebContext. An ephemeral #WebKitWebContext is a context
created with an ephemeral #WebKitWebsiteDataManager. This is just a convenient method
to create ephemeral contexts without having to create your own #WebKitWebsiteDataManager.
All #WebKitWebView<!-- -->s associated with this context will also be ephemeral. Websites will
not store any data in the client storage.
This is normally used to implement private instances.
