Add SkCodec::FrameInfo::fFullyReceived

This indicates whether the frame has been fully received, i.e. the
stream contains enough data to decode to the end of the frame.

A client may want to use this to know whether they should attempt to
decode this frame, if they do not want to decode partial frames.
