Revert "ccpr: Draw curves in a single pass"

This reverts commit df04ce29490a24f9d5b4f5caafd8f6a3368a19e0.

Reason for revert: Going to revisit AAA quality

Original change's description:
> ccpr: Draw curves in a single pass
> 
> Throws out the complicated MSAA curve corner shaders, and instead just
> ramps coverage to zero at bloat vertices that fall outside the curve.
> 
> Updates SampleCCPRGeometry to better visualize this new geometry by
> clearing to black and drawing with SkBlendMode::kPlus.
> 
> Bug: skia:
