Revert "Remove GrDrawAtlasOp"
This reverts commit 97d957d1db657f8bbcec3db5fdddd5868ab9512e.
Reason for revert: Looking at perf, desktop GPUs get better, many mobile GPUs get worse.
Original change's description:
> Remove GrDrawAtlasOp
>
> The base device turns drawAtlas into drawVertices, which ends
> up being *faster* (in my tests) than our specialized code.
>
> It's certainly possible to write a custom version that's better,
> but for now, it seems better to just do this.
>
