Reland of Injectable Obj-C video codecs (patchset #1 id:1 of https://codereview.webrtc.org/2975963002/ )

Reason for revert:
New CL for fixing the issues

Original issue's description:
> Revert of Injectable Obj-C video codecs (patchset #8 id:140001 of https://codereview.webrtc.org/2966023002/ )
>
> Reason for revert:
> Causes no video in certain scenarios. Please come up with a test plan or unit test to prevent such problems in the future.
>
> Original issue's description:
> > Injectable Obj-C video codecs
> >
> > Initial CL for this effort, with a working RTCVideoEncoder/Decoder for H264
> > (wrapping the VideoToolbox codec).
> >
> > Some notes / things left to do:
> >   - There are some hard-coded references to codec types that are supported by
> >     webrtc::VideoCodec, cricket::VideoCodec, webrtc::CodecSpecificInfo etc
> >     since we need to convert to/from these types in ObjCVideoEncoder/Decoder.
> >     These types would need to be more codec agnostic to avoid this.
> >   - Most interfaces are borrowed from the design document for injectable
> >     codecs in Android. Some data in the corresponding C++ classes is discarded
> >     when converting to the Obj-C version, since it has fewer fields. I have not
> >     verified whether all data that we do keep is needed, or whether we might be
> >     losing anything useful in these conversions.
> >   - Implement the VideoToolbox codec code directly in the RTCVideoEncoderH264
> >     classes, instead of wrapping webrtc::H264VideoToolboxEncoder / decoder.
> >     Eliminates converting between ObjC/C++ types outside the ObjCVideoEncoder/
> >     Decoder wrapper classes.
> >   - List the injected codec factory's supported codecs in the list of codecs in
> >     AppRTCMobile.
