Revert "Prefer GrAAConvexPathRenderer over ccpr"

This reverts commit c00e47054744c4b6733a129b9cfc372d2085899e.

Reason for revert: Appears to fix flakiness on NUC5PPYH-Vulkan

Original change's description:
> Prefer GrAAConvexPathRenderer over ccpr
>
> Even though ccpr can be faster than the convex renderer for small
> paths, there is value in a simpler, more consistent approach. The
> convex renderer is single-pass, doesn't deal with caching, and is
> unaffected by the less favorable flush pattern in Chrome. We can
> address the regressions from this CL by optimizing single-pass convex
> path rendering, rather than trying to use ccpr more.
