Bug 1550351 [wpt PR 16665] - Reland "Disallows reusing RTCIceTransport.", a=testonly

Automatic update from web-platform-tests
Reland "Disallows reusing RTCIceTransport."

This is a reland of 1aaab3f0a1f80b72eaf47427842e847e8413b994

Original change's description:
> Disallows reusing RTCIceTransport.
>
> Currently if an RTCIceTransport that comes from an RTCPeerConnection is
> reused to create and RTCQuicTransport there is a crash. This disallows
> this from happening by throwing an exception if the client attempts to
> do this.
