Detect empty triangles in CropRect
Fixes a rare case when using the experimental_DrawEdgeAAQuad API with
a degenerate quadrilateral that forms a triangle. In this case, the
GrQuadUtils::CropRect code would sporadically calculate invalid barycentric
coordinates that then suggested the triangle contained the entire render
target. The quad optimizations would then replace that with a fullscreen
clear.
