Dor Hen d1831cb4f8 Treat non DTLS/SCTP Protocol Based Data Channels as Unsupported Media
In current state, the SDP parser in webrtc is not backward compatible with clients that might still be using RTP data channels.
Obviously, this isn't there is no such usecase in webrtc since the code is deleted, but in Meta we still use it and would like
to be able to negotiate between clients that offer RTP data channels.
Instead of erroring the parsing procedure, we can parse it as unsupported media in the client that no longer supports RTP data channels.

Replaced the existing test that expects parsing failures with a test that validates that the content was parsed as unsupported media.
