Revert "Remove GrPipeline from GrDrawOp."

This reverts commit 2bf4b3a97b770811d9e0558dbbfbdb57cfafbdb7.

Reason for revert: nanobench assertion

Original change's description:
> Remove GrPipeline from GrDrawOp.
> 
> GrDrawOp subclasses are now free to construct their pipelines at flush time and now in theory could use multiple GrPipelines for multipass rendering.
> 
> GrProcessorSet may be used to retain the processors from a GrPaint with "pending execution" style refs.
> 
> NVPR and Instanced rendering are updated to create their pipelines at flush time without a GrPipelineBuilder.
> 
> The monolithic pipeline creation/management that was on GrDrawOp is moved to GrMeshDrawOp. However, this is temporary and will be removed in coming changes.
