Uses the Sutherland–Hodgman algorithm of progressively clipping each side, so may leave folded overlaps directly on the boundaries if applied to non-convex polygons (but otherwise should still work)

- remove TGeneralPolygon2 and IntBoxTypes.h copy constructors, to allow everything to be autogenerated (especially so that a proper move should be generated for TGeneralPolygon2)
- add explicit moves + delete copies for TSparseGrid3 and FProgressCancel::ProgressScope, as these have custom destructors and the default move/copy behavior would cause bugs
- make voro++ move assignment protect vs self-move

ModelingTools: Add option to Weld Tool to try to resolve T-junctions. Add feedback to report back the initial and final number of open boundary edges.

GeometryCore: Add bClearExisting option to FDynamicMeshAttributeSet::EnableMatchingAttributes(). Default true is old behavior. New behavior, when false, is to preserve existing attribute set counts/values. Also now copying group and weight layer names if not set.
ModelingTools: CombineMeshesTool now uses EnableMatchingAttributes instead of only explicitly matching UV layers, so group and weight layers are copied properly to duplicates
MeshConversion: DynamicMeshToMeshDescription now generates unique names in ConvertPolygroupLayers and ConvertWeightLayers. Previously if multiple attribs had the same name (eg NAME_None), output MeshDescription would only have a single attrib w/ that name

all the voxels in a block far from the mesh surface should share the same state (inside or outside) for water-tight meshes, but the counting method used for sign assignment may produce odd results for non water-tight meshes where the block may have both inside and outside elements. this change accounts for that behavior.

1. Actually use the SpatialLevels argument
2. Only allow early stopping at level boundaries, so the priority ordering can properly sort points at the same spatial level. Fixes points being spatially clumped when early stopping is enabled.
3. Stop referring to some of the importance weights as "curvature" (we often weight by things other than curvature)
4. Expose OffsetResFactor to allow more control of how clumpy the distribution is (value was hardcoded at 4, but I think 1 or 2 tends to space things better)

Should be faster in most practical cases, though can be slower if an inserted edge must cross a lot of existing edges.
