Bug 1501: Graph Delaunay: Use default winding outer-boundary:=CCW and inner-hole:=CW w/o using winding determination (might be incorrect)

This simplifies our code further and it has been validated that our polygon shoelace-algo for area >= 0 ? CCW
doesn't produce correct results with all curves.
Hence rely on given winding depending on outer-boundary and inner-hole if CDTriangulator2D.FixedWindingRule == true (default and fixed).

This also removes the more costly winding shoelace calculus,
hence Outline ctor only sets dirtyWinding:=true w/o calculating the winding.
