Revert of change pixel-serializer to support reencoding existing data (patchset #5 id:80001 of https://codereview.chromium.org/1373683003/ )

Reason for revert:
Need to somehow get access to encoders in chrome -- link error on the roll since SkImageEncoder is not built as part of chrome.

Original issue's description:
> change pixel-serializer to support reencoding existing data
>
> Trying to evolve this interface so it can
> - support rich set of backend-encoders (including ones like ETC1 that can cheaply convert to KXT
> - allow for encoding images as well as bitmaps (e.g. for picture serialization)
> - perhaps replace SkImageEncoder as an API (assuming we create a factory that returns a serializer given a format)
