GrQuadEffect and GrConicEffect were the only FPs that supported the
HairlineAA clip-edge type. These FPs have been updated to implicitly
always use HairlineAA, and other FPs no longer need to consider the
HairlineAA case.
This CL also updates the bezier-effects GM images to remove the non-
hairline test columns.
