Add SkCodec::Result indicating error in the data
Previously, SkGifCodec treated an error in the LZW data as incomplete,
since we can still draw the partially decoded image. But a client doing
incremental decodes needs to distinguish this from truly incomplete
data. In the case of an error, the client should not attempt to provide
more data and decode again.
Add kErrorInInput, and return it when SkGifCodec sees a fatal error.
Treat it the same as kIncompleteInput when it comes to filling and DM.
