swig/java: basic encode support

Browse Source 
Wrap WebPEncode???* to provide an interface similar to decode.
As only WebPGetEncoderVersion is wrapped directly from encode.h avoid
including it in the swig file to reduce %ignore's.
This change also removes unnecessary incremental decoding related enums.
