Original change's description:
> Optimize GrTessellatePathOp's code to emit inner triangles
> 
> Previously we used a naive algorithm to generate "middle-out" topologies
> for inner polygons, including copying all endpoints to a new array.
> 
> This CL adds a "GrMiddleOutPolygonTriangulator" class that
> accomplishes the same thing in 1/5th the time using a small O(log N)
> stack.
