When injecting video codec factories in the Obj-C SDK, use the new
peer connection API that uses webrtc::Video{De,En}CoderFactory classes
and does not automatically add internal software codecs. Instead the
injected factory can support internal VP8 and VP9 codecs through the
included Obj-C classes RTCVideo{De,En}coderVP{8,9}.
When not explicitly injecting any video codec factory, the old code
path is still used and injects only H264 as an external codec and
the internal codec factory is used.
