Allow video frame gaps in packet buffer for H.264

With LTR and SVC etc., H.264 should be able to skip lost frames, and continue to play from the new frames. With DependencyDescriptor, it is allowed to reference the previous frames, even there is a gap in the middle. However, we found there is a special logic for H.264 in packet_buffer.cc, which requires no gap for H.264.

We should allow gaps if the packet has GenericDescriptorInfo (either GenericDescriptor or DependencyDescriptor header extension).
