LUCENE-8712: Polygon2D does not detect crossings in some cases (#598)
LUCENE-8712: revert crossing logic to use boolean logic and skip lines
over the dateline to support dateline crossing logic

> Polygon2D does not detect crossing if the triangle crosses through points of
> the polygon and none of the points are inside it. For example:
>
> {code:java}
> public void testLineCrossingPolygonPoints() {
> Polygon p = new Polygon(new double[] {0, -1, 0, 1, 0}, new double[] {-1, 0,
> 1, 0, -1});
> Polygon2D polygon2D = Polygon2D.create(p);
> PointValues.Relation rel =
> polygon2D.relateTriangle(GeoEncodingUtils.decodeLongitude(GeoEncodingUtils.encodeLongitude(-1.5)),
> GeoEncodingUtils.decodeLatitude(GeoEncodingUtils.encodeLatitude(0)),
> GeoEncodingUtils.decodeLongitude(GeoEncodingUtils.encodeLongitude(1.5)),
> GeoEncodingUtils.decodeLatitude(GeoEncodingUtils.encodeLatitude(0)),
>
> GeoEncodingUtils.decodeLongitude(GeoEncodingUtils.encodeLongitude(-1.5)),
> GeoEncodingUtils.decodeLatitude(GeoEncodingUtils.encodeLatitude(0)));
> assertEquals(PointValues.Relation.CELL_CROSSES_QUERY, rel);
> }{code}
> [~nknize] you might want to look at this as I am not sure what to do.
