Add UMeshVertexPaintTool, subclass of UMeshSculptToolBase. Paints Mesh Vertex Colors (ie Asset colors, not instance colors). Provides many interactions similar to GroupPaintTool (ie brush paint, click-to-fill, poly-lasso, volumetric vs connected brush ROI, UV/Normal seams, visibility filter, etc. Supports painting split-vertex colors, or smooth per-vertex colors (bHardEdges setting). Supports various brush types (paint, smooth, "blend" = average split values). Painting supports custom color-blend modes (ie "over" mode, does stroke compositing like pixel painting tools). Can show vertex color under cursor. Supports showing vertex color or original materials. Ability to filter channels for visibility/painting. Actions buttons to fill current-color/black/white. "Utility" panel for common operations (blend all seams, fill channels, invert channels, copy channel to channel, swap channels, copy from weight map, copy to all/single LOD).
Internally supports seam painting by splitting all colors on startup (ie to create per-triangle-vertex color) and then welding on shutdown.
Current auto-RGBA conversions are inverted, internally the tool works in Linear colors, preview DynamicMeshComponent is configured to convert to SRGB in color buffers (similar to static mesh).
Vertex color brush ops added in MeshVertexPaintBrushOps.h, deriving from new FMeshVertexColorBrushOp. Various color-blending functions implemented there, should be moved to centralized place eventually.
Expose MeshVertexPaintTool in ModelingMode
Add FModelingToolsColorChannelFilter, for toggling R/G/B/A filtering state, and a details customization that shows these four checkboxes in a horizontal row. Use in MeshVertexPaintTool, Register in Modeling Mode.

- Add a Gradient Interaction Type. The user selects "high" and "low" vertices and a gradient is automatically computed between them

Selection enable/disable can now be toggled dynamically via mode settings popup, toolbar will hide/show based on current setting state.
GeometrySelectionManager is now always created. New Mode function GetMeshElementSelectionSystemEnabled() indicates whether selection is currently enabled, when disabled active targets will not be tracked.
Selection Toolbar icons now are disabled while in a Tool (as selection system is not active then)
New Static Mesh Assets and Volumes created using Modeling Tools now default to unlocked, via new functions on StaticMeshSelector / Volume Selector.
Unlocked Asset/Volume sets are cleared on level change
Added cvars modeling.Selection.EnableStaticMeshLocking and modeling.Selection.EnableVolumeLocking which can be used to fully disable lock-ability of StaticMesh/Volume (default true)
shortened some names of tool group tabs, as labels are now shown and long names make the bar wider
Added a few toast notifications for when setting state changes require a mode or editor restart.

ModelingComponents: Add ShapeSet member for passing simple collision shapes in FCreateMeshObjectParams, support in relevant functions in UEditorModelingObjectsCreationAPI. Add UE::Geometry::GetCollisionShapes() functions in ComponentCollisionUtil.h, and update various functions to support DynamicMeshComponent
DynamicMeshComponent: change signature of GetSimpleCollisionShapes() to return const ref

- Warn about artifacts on meshes with open boundaries
- Fix some settings not being saved/restored
- Fix transaction name on undo/redo not matching the tool name
Also: Make the asset warning for base interactive tool only clear the tool's display message if it set a display message when it was last called, so that it is less likely to clear unrelated display messages when called with no warning to display.

Add IGeometrySelectionTransformer::PreviewRender() API, for rendering info during selection transforms. Currently being called by UGeometrySelectionManager::DebugRender() for active transforms.
FBasicDynamicMeshSelectionTransformer implements PreviewRender, draws selected mesh edges (tris as edges) and vertices, as well as affected edge ROI.
FDynamicMeshPolygroupTransformer overrides this behavior and draws polygroup edges/verts and edge ROI
FStaticMeshSelector and FVolumeSelector now create FDynamicMeshPolygroupTransformer for polygroup selections
FBasicDynamicMeshSelectionTransformer::bEnableSelectionTransformDrawing flag controls whether this edge drawing is enabled. Disabled on DynamicMeshComponent, enabled on StaticMesh and Volume.
Add Normals recomputation during tri and polygroup transforms in FBasicDynamicMeshSelectionTransformer and FDynamicMeshPolygroupTransformer
Add FGroupTopologyDeformer::EnumerateROIEdges() util function to support above
