Revert of Make SkPicture/SkImageGenerator default to SkCodec (patchset #7 id:120001 of https://codereview.chromium.org/1671193002/ )

Reason for revert:
Breaks Ubuntu and Mac CMAKE

Original issue's description:
> 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.
