Marina Ciocea dc69fd2b80 [InsertableStreams] Fix video sender simulcast.
The transformer was previously moved into the config of the first stream
which resulted in incorrect behavior for simulcast. Use the transformer
in all the streams.

Pass the sender's ssrc on registring the transformed frame callback, to
associate separate transformer sinks for each sender.
