Generalize the `extractFaceOffset` method to `getOffsetArea`, which can handle both face offsetting and projection. Another difference is that the new method exposes Area's ability to preserve internal holes, defaulting to preserving. The method is moved to the PathUtils module, reflecting its generality and fairly wide used across Path. This method is then used to provide a drop-in alternative to `FindUnifiedRegions` via a small wrapper in PathSurfaceSupport. The Area implementation is generally quick, but can fail (throw) in some cases, so the wrapper is trying the Area method as an optimization first, and falls back to the full `FindUnifiedRegions` logic if that fails.
