Greg Daniel bcf612b5d0 Revert "Revert "Plumb the use of GrBackendRenderTarget throughout Skia"" 
This reverts commit e3bd422faf.

Reason for revert: Pre-req changes have all landed in other projects at this point.

Original change's description:
> Revert "Plumb the use of GrBackendRenderTarget throughout Skia"
> 
> This reverts commit fdd77daedb.
> 
> Reason for revert: Apparently I have a few more build files to update before this can land.
