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. > > BUG=skia:4691 > BUG=skia:4290 > GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1671193002 > > Committed: https://skia.googlesource.com/skia/+/026388a01864c74208ad57d1ba4f711602d101c6 TBR=msarett@google.com,reed@google.com,scroggo@google.com # Skipping CQ checks because original CL landed less than 1 days ago.
