d20f4f4012 Fixes to FPriorityOrderPoints:
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)

bc7cab5826 Geometery Core: extends the blocked 3d grids and adds narrow band sparse SDF generation using these blocked grids.
unittests are included for the blocked grids and sdf generation, as well as benchmarks for sdf generation.
( This CL flushes out an old shelf of Ryan's.)

172058c824 GeometryCore:
- add FColliderMeshProjectionTarget to allow a FColliderMesh to be used as a projection target
- remove dead code from TDenseGrid3
- add TBlockedDenseGrid3, variant of TDenseGrid3 that lazy-allocates sub-blocks of a dense grid, to reduce memory usage in sparse/narrow-band situations on large uniform grids
- replace usage of TDenseGrid3 in FMarchingCubes with TBlockedDenseGrid3, to reduce memory footprint on large meshing problems

fc967a2d79 Add structured down-sampling options to custom voronoi point sets, to allow less-clumped / sharp-edge-favoring down-sampled point sets from meshes and bones
Add a FPriorityOrderPoints class to help with downsampling, implementing a similar algorithm to what is used by physics to help choose collision sample points as a subset of mesh vertices but more generally accessible

MeshLaplacian.{h,cpp}                - Adds new enum types for Intrinsic Delaunay Triangulation (IDT)  Laplacians
LaplacianOperators.{h,cpp}           - Adds wrappers and allow enum switches to build IDT Laplacians if requested
LaplacianMatrixAssembly.h            - Actually construction of IDT Laplacian.

e3183cb1e7 GeometryProcessing: clean up mesh timestamps.
- remove FDynamicMesh3::Timestamp (unused), rename Shape/Topology Timestamps to Shape/TopologyChangeStamp, change to atomic<uint32>
- add FDynamicMesh3::bEnableShapeChangeStamp, default to false, to disable ShapeChange tracking. Add ::SetShapeChangeStampEnabled() and ::HasShapeChangeStampEnabled() to configure.
- replace FDynamicMesh3::UpdateTimestamps() with UpdateChangeStamps()
- add bTrackChange param to FDynamicMesh3::SetVertex(), optionally updates ShapeChangeStamp (if enabled). Default true. Remove SetVertex_NoTimeStampUpdate(), update call sites.
- add FDynamicMesh3::GetChangeStamp(), returns combination of Shape and Topology stamps as uint64
- rename TTriangleMeshAdapter::GetTimestamp() to GetChangeStamp(), update usages
- remove TPointSetAdapter::Timestamp()   (was not used in code)
- update TMeshAABBTree3 to use GetChangeStamp(), update internal checks to call IsValid() instead
- update TFastWindingTree w/ similar changes
- update calls in UVEditor, may require further updates
