fixup winding contours

Add AsWinding to convert SkPath with even odd fill to winding fill.

This basic implementation works for simple non-intersecting paths.
It may fail if contours in paths touch, specifically when the leftmost
point in a contour is shared with another contour.

The incomplete parts are marked with TODO in the code.

If this interface and implementation look promising, I will continue to
tackle the more difficult cases.
