Revert of Raster into an SkP before rendering a DisplayList.

Revert of Raster into an SkP before rendering a DisplayList. (patchset #2 id:20001 of https://codereview.chromium.org/966443003/)

Reason for revert:
Fails several slimmingpaint layout tests on Linux

Failures that look to be real bugs include:

  virtual/slimmingpaint/fast/table/border-collapsing/adjacent-row-groups-multi.html
  virtual/slimmingpaint/fast/text/emphasis.html

Original issue's description:
> Raster into an SkPicture before rendering a DisplayList.
>
> Rasterizing a display list is more than 2x slower than rasterizing in the existing architecture. This is due to recording more with a display list and we have no bounding hierarchy to cull content quickly.
>
> We can address this by creating an SkPicture from the list, with a bounding hierarchy, and rasterizing that instead. The result is slightly faster than the non-S.P. pipeline but uses 2x more memory.
