Revert of default SkPixelSerializer (patchset #2 id:20001 of https://codereview.chromium.org/1507123002/ )

Reason for revert:
I was overconfident.

Original issue's description:
> default SkPixelSerializer
>
> Add SkImageEncoder::EncodeData(const SkPixmap&, ...) function.
>
> Add SkImageEncoder::CreatePixelSerializer() to return a
> PixelSerializer that calls into SkImageEncoder::EncodeData.
>
> SkImage::encode() make use of SkImageEncoder::CreatePixelSerializer.
