Create a new 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
WebKitWebViews 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.
