* sfu: filter VP8 temporal layers by frame when the dependency descriptor is sent

With the dependency descriptor, libwebrtc sends a one byte VP8 payload
descriptor without a picture ID, so the VP8 munger's picture ID based
temporal drop logic stops filtering after the first gap. A new VP8DD codec
munger decides once per frame from the descriptor's frame number and
temporal ID and applies that decision to every packet of the frame.

* sfu: use the VP8 munger when picture IDs come with the dependency descriptor

VP8DD needs the one byte VP8 payload descriptor that libwebrtc sends with
the dependency descriptor. If a publisher keeps picture IDs next to the
descriptor, they need rewriting, so the forwarder switches to the VP8
munger and keeps switching temporal layers with the descriptor.
