Change most WebSocketStreamCreate*Tests to use wss scheme.

Most of these tests will be adopted to test WebSockets over HTTP/2 as
well, but that only works with wss.  Also, change hosts and origins from
localhost to www.example.org instead so that it works with the test
certificate.

Also, change WebSocketStreamCreateUMATest to be a derived class of
WebSocketStreamCreateTest instead of creating an instance of it.  This
will also help with turning this into a parametrized class.
