Cast: Remove TRANSPORT thread and get rid of Unretained in sender

There is no need to have a separate TRANSPORT thread to call
CastTransportSender. It is supposed to be owned by an external body so
we can just establish the contrast that it is always called on the
cast MAIN thread.

After this change there is no Unretained in the cast sender.
