- add 2D version of VectorTanHalfAngle to VectorUtil.h
- add FDynamicMeshUVEditor::SetToPerVertexUVs, initializes overlay to have a single UV for each vertex
- add FQuadGridPatch::InitializeFromQuadPatch(), initializes the quad grid from external rows of quads and associated vertices
- add FQuadGridPatch::GetVertexColumn(), returns the list of vertices in a specific grid column
- add FQuadGridPatch::FindColumnIndex(), finds the index of the grid column that contains a specific Vertex ID

also do some cleanup / generalization of the utility functions and change geometry script's append simple collision function to use them.

- More aggressively prune the cache of computed merge shapes after it reaches a threshold size
- By default compute a proximity graph based on actual proximity, not the full n^2 possible connections
- After finding the best of a number of possilbe merges, optionally only look for local improvements to the current best rather than doing a full search for the absolute best connection.

* Removed old ExportToRawMesh function and CVar `landscape.Nanite.MarchingSquaresVisibility`
* Make Landscape Nanite build less noisey in the logs
* GeometryCore - Added Reserve to TPointHashGrid2 (to match TPointHashGrid3)

Add a face normal clustering function that returns the vertices at corners of the clusters (vertices touching at least 3 different clusters), for use in the angle-tolerance convex hull simplification method

Use this algorithm in the polygroups generator tool, so we get more useful groups on smooth surfaces (like a cylinder)
Also add a helper to the FSizedDisjointSet class to easily get the number of groups in the set and a mapping between compact group indices and sparse group IDs

Add a 'source ID' concept to the convex part decomposition, to enable tracking of which hulls were not merged to any other hulls when running the convex hull merging algorithm.

Note: These settings were all introduced post-5.3, so moving them should not require deprecation
