Revert of make drawImage a virtual on SkDevice (patchset #3 id:40001 of https://codereview.chromium.org/1118823004/)

Reason for revert:
need to make serialization work for pictures, now that images are "real"

Original issue's description:
> make drawImage a virtual on SkDevice
>
> default impl will turn the Image into a (raster) bitmap and call drawBitmap.
