Revert of Retract PipelineBuilder some more (patchset #9 id:160001 of https://codereview.chromium.org/2092893003/ )

Reason for revert:
skbug.com/5559

Original issue's description:
> Retract PipelineBuilder some more
>
> The main part of this CL is widening SkDrawContext::drawBatch's API to accept the userStencilSettings & drawFace
>
> There is some ancillary spookiness related to expanding the should_apply_coverage_aa & mustUseHWAA methods to encompass mixedSamples
>
> Calved off:
> https://codereview.chromium.org/2165283002/ (Remove DrawFace enum from GrPipelineBuilder)
> https://codereview.chromium.org/2167183002/ (Minor change to Ganesh path renderers)
>
> GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2092893003
>
> Committed: https://skia.googlesource.com/skia/+/2895eeb11a9f0d9c0018d49dd4bc45f6c6fc062c
