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.

Benchmark configuration:
- Test scene with 4 meshes: a mossy stone nanite mesh, a beach ball, a ball with an emissive blue cross and a hut mesh
- Target mesh: 11.8k triangles mesh, created by voxel wrapping the meshes in the test scene elements
- 4096x4096 output texture with 16x multisampling baking BaseColor, Emissive, PackedMRS and Normal maps
- 4096x4096 photo capture resolution
Unreal Insights reports the following times for the Bake call:
- Before this change: 2 mins 45 seconds
- After this change: 55.9 seconds
Aside: (Unaffected by this change) In both cases the photo capture, which is done on the game thread, took about 1 min

- Constrained edges along a boundary are allowed to collapse, and vertices are allowed to move, but they are projected back to the original boundary curve geometry
- Additionally, vertices at boundary "corners" (defined using an angle threshold criterion) are constrained to not move or be deleted
