This CL introduces a new feature enabling video packet send batches. The feature is enabled via PeerConnectionInterface ::RTCConfiguration ::MediaConfig ::enable_send_packet_batching. PacketOptions have been augmented with attribute "batchable" (set for all video packets) and attribute "last_packet_in_batch" which gives injected AsyncPacketSockets a chance to understand when a batch begins and ends. When the feature is on, packets are collected in RtpSenderEgress. On reception of OnBatchComplete from PacingController, RtpSenderEgress sends the collected batch, setting "last_packet_in_batch" to true in the last packet.
