Revert of SkScaledCodec class (patchset #35 id:680001 of https://codereview.chromium.org/1260673002/ )
Reason for revert:
breaking ubuntu bots
Original issue's description:
> SkScaledCodec class
>
> This class does scaling by using a scanlineDecoder.
> getScanlines and skipScanlines are used for y sampling,
> the swizzler is used for x sampling
>
> this class is currently only working for png and jpeg images
> I will update other Codec types to work soon
>
> For SkJpegCodec to implement width wise swizzling it now
> uses a swizzler. I ran performance tests on this change.
> Here are the performance test results:
