While Boolean is not guaranteed to work if the operands are not volume-enclosing (technically: PWN - piecewise constant winding number), it needs to do something in those cases. This change makes more cases meet user expectations in T84493, T64544, T83403, T82642 (though very slow on that one). The original new boolean code used "generalized winding number" for this fallback; replaced this with code that uses raycasting. Raycasting would have been faster, but for unfortunately also switchd to per-triangle tests rather than per-patch tests since it is possible (e.g., with Suzanne) to have patches that are both inside and outside the other shape. That can make it much slower in some cases, sadly.
