webrtcbin: Enforce m-line restrictions when creating offer

First fail the offer creation if the mid of an existing offer doesn't
match a forced m-mline.

Then, for all newly added mlines, first look for a transceiver that
forces this m-line, then add a "floating" one, then the data channel.
And repeat this until we're out of transceivers.
