Make SkPicture/SkImageGenerator default to SkCodec

Remove reference to SkImageDecoder from SkPicture. Make the default
InstallPixelRefProc passed to CreateFromStream use
SkImageGenerator::NewFromEncoded instead.

Make SkImageGenerator::NewFromEncoded create an SkCodecImageGenerator.
Remove the old version that used SkImageDecoder.

Remove all versions of lazy_decode_bitmap/LazyDecodeBitmap. The default
now behaves lazily.

Update all clients to use the default.

Move SkImageDecoderGenerator into KtxTest.cpp, and use it directly.
