This change ultimately enables wiring up VideoRtpReceiver::OnGenerateKeyFrame and
OnEncodedSinkEnabled into internal::VideoReceiveStream so that encoded frames
can flow to sinks installed in VideoTrackSourceInterface.

By using the top level VideoCodec maxFramerate, the FrameBufferController
would sometimes not use the intended value for each simulcast layer.
In the case of "conference mode", top level maxFramerate was set to 5,
which matches the lower layer but is different from the overall maximum
maxFramerate which would be 60.

Static libraries don't guarantee that an exported symbol gets linked
into a shared library (and in order to support Chromium's component
build mode, WebRTC needs to be linked as a shared library).
Source sets always pass all the object files to the linker.
On the flip side, source_sets link more object files in release builds
and to avoid this, this CL introduces a the GN template "rtc_library" that
expands to static_library during release builds and to source_set during
component builds.

Summary:
There is an issue with WebRTC for handling of certain H.264 bitstreams where the packets forming the H.264 stream has non-zero packets before the packet containing SPS.
Typically a IDR (key frame) will have SPS/PPS (if present) or the IDR slice in the first packet.
But this is not required in all cases, for example when packetization-mode = 0, you can have each NALU in separate packet. And certain NALUs can exist before SPS, for example SEI, AUD.
The way WebRTC associates width/height to encoded frames is by tracking the dependency of IDR slices to SPS/PPS.
RTP packets containing SPS/PPS have correct width/height stored in them during parsing of SPS in RtpDepacketizerH264::ProcessStapAOrSingleNalu
IDR packets refer to SPS using ppsid, spsid and the width/height fields get transferred from packet containing SPS to IDR packet in H264SpsPpsTracker::CopyAndFixBitstream.
When packets are assembled into a single encoded H264 frame in PacketBuffer::FindFrames, the loop goes through all the packets/nalus in backward scan from last RTP packet of IDR to first one.
Hence the order of NALUs during this scan is : Last parts of IDR Slice -> Mid parts of IDR Slice RTP packet -> first IDR slice Packet (this should have correct width / height) -> RTP packet containing SPS/PPS (this should have correct width/height)
start_index points to the first RTP packet of the frame and its passed into RtpFrameObject's constructor. RtpFrameObject will use the width/height stored in first RTP packet.
This works fine as long as the first RTP packet has width/height, which will be the case if first RTP packet is IDR or SPS.
In H.264 first RTP packet may be AUD, SEI in those cases, RtpFrameObject will create IDR with width/height = 0 and this causes problem for Android hardware decoders.
On Android hardware decoders rely on correct width/height to initialize the hardware decoder.
Verified on real scenario that we have.

Before this change all layers were glued together at the receive side
into a single IVF frame. This confuses most bitstream parsers.
Since this change all spatial layers would be written as separate frames
on the receive side also (on the send side it's already done that way).

This issue happens for default case sps_pps_idr_is_h264_keyframe_ is false
The way PacketBuffer::FindFrames works for H264 is it keeps on skipping the packets till it finds a packet which has last=1
This is checked here : if (sequence_buffer_[index].frame_end)
Inside this block there is a loop, to go back and scan all the packets till start of the frame.
Since the scan is backwards, the sequence of nalus in this scan is IDR -> PPS -> SPS.
Once IDR is detected if (h264_header->nalus[j].type == H264::NaluType::kIdr) , the code will has_h264_idr = true.
When it scans the previous packets, it skips those as has_h264_idr is true. These packets have the SPS / PPS and hence has_h264_sps / pps flags were never set to true.
This resulted in warning as no SPS/PPS has been found for IDR.
Test plan : verified loopback call on IOS simulator using H264 codec and the warning log "Received H.264-IDR frame..." is not present anymore

This CL adds an optional second encoder factory to SimulcastEncoderAdapter,
that can be used to create software fallback adapter per simulcast layer.
It also adds logic to check if the encoder supports simulcast natively, if so
it only allocates a single instance and delegates the simulcast logic to that
encoder instead. This means we will be able to remove EncoderSimulcastProxy.
