ryan schmidt 6191a7ce3c ApproximateActors updates: ...

- FMeshSceneAdapter updates
   - if bThickenThinMeshes is enabled, then all instance meshes are converted to DynamicMesh and decomposed to find non-closed regions. Those regions are uniqued into separate meshes. The remaining closed geometry is separated out and kept as instanced.
   - various utility functions added to support above
   - previous code to explicitly 'thicken' open meshes into solids is removed. Instead unsigned distance is used to determine inside/outside and generate a 1/0 winding number
   - instances are now sorted into an octree to speed up winding number evaluations
   - If all meshes are closed (or effectively closed via above, ie will return integer winding number) then winding number query can early-out as soon as it finds a non-zero value
- Add hard-normals options in IGeometryProcessing_ApproximateActors (not exposed in MergeActors tool options yet)
- Added hard-normal callucation to ApproximateActorsImpl, and additional profiling
- Allow specification of actual  ECollisionTraceFlag options in CreateStaticMeshUtil, instead of just a boolean
- Add FSparseDynamicOctree3::ContainmentQueryCancellable() variant that can early-exit
