* join dns with another instance of WS transport

Secure Websocket transport needs unresolved addresses, so we join DNS transport with
yet another instance of Websocket transport.

Closes #12024

* WSS transport itself need to wrap DNS transport

in order to resolve addresses before passing them down to TCP transport

Refs https://github.com/libp2p/rust-libp2p/issues/3330

* reverse order

* simplify code: remove WS from WSS inner DNS transport

* remove the 2nd instance of WS transport
