fixes for potential crash / invalid operations on radial fracture of pillar
- make 'embed surface path' find the intended start vertex for its path when it's known
- guard against path being empty before accessing element 0
- guard against invalid edge collapse in mesh boolean that was triggered by this example

[CL 16775195 by Jimmy Andrews in ue5-main branch]
ModelingTools: Expose Simplify To Minimal Planar simplification mode in Simplify Tool. Add edge filter to this simplification mode in TMeshSimplification. Add support for returning all edges along intersection curves in FMeshBoolean and FMeshSelfUnion. Add option BooleanMeshesOp and SelfUnionMeshesOp to apply minimal-planar simplification along these cut/intersection edges. Expose as toggles in CSGMeshesTool and SelfUnionMeshesTool

+ also improves texturing options for generalized cylinder (needed b/c that's what we use to make the cutting geometry)
+ also separates the "embedded edges" concept from the "error / problem" edges, and always visualizes the embedded edges (for the boolean, these are different edges; also visualizing the embedded edges makes it a lot easier to understand what the "Insert Polygon" option is doing)

- Use octree to speed up closest-edge finding
- Center and rescale data before computing intersections (and put back to original space after operation is complete)
- Add option to skip edge welding, matching MeshBoolean
- Minor comment and variable name cleanup
