Revert "Don't ignore degenerates when deciding if a path is convex"
This reverts commit 53cd6c4331a2ef21a7c5eb6166c782cd33178a7b.
Reason for revert: Temporary to limit gold cross-talk with other CLs.
Original change's description:
> Don't ignore degenerates when deciding if a path is convex
>
> This ensures that a path with a second contour will always be marked
> concave. GrDefaultPathRenderer was incorrectly drawing paths of this type
> (thinking that it could fill them with simple triangulation).
