Revert of Sketch splitting SkPicture into an interface and SkBigPicture. (patchset #22 id:420001 of https://codereview.chromium.org/1112523006/)

Reason for revert:
speculative revert to fix failures in DEPS roll

Original issue's description:
> Sketch splitting SkPicture into an interface and SkBigPicture.
>
> Adds small pictures for drawRect(), drawTextBlob(), and drawPath().
> These cover about 89% of draw calls from Blink SKPs,
> and about 25% of draw calls from our GMs.
>
> SkPicture handles:
>   - serialization and deserialization
>   - unique IDs
>
> Everything else is left to the subclasses:
>   - playback(), cullRect()
>   - hasBitmap(), hasText(), suitableForGPU(), etc.
>   - LayerInfo / AccelData if applicable.
>
> The time to record a 1-op picture improves a good chunk
> (2 mallocs to 1), and the time to record a 0-op picture
> greatly improves (2 mallocs to none):
>
>     picture_overhead_draw:   450ns -> 350ns
>     picture_overhead_nodraw: 300ns -> 90ns
