* Fixed a crash that occurred in the baking step when cancelling a scene capture which was triggered by changing an option which invalidated all photo sets (i.e., render capture resolution or capture anti aliasing). This was occurring because the baking step proceeded after the scene capture cancellation and the needed photosets were empty.
* Fixed a crash which can happen if you have no channel enabled, change cleanup tolerance from 0 to 1 and then enable the BaseColor channel. This was fixed by changing the behavior of the Cleanup Threshold property, if its positive the DeviceDepth capture is enabled and its disabled otherwise, previously we also required that another channel was enabled which led to the crash in the baking step. The new semantics are easier to understand in the code and and is probably an improvement to the UX as well since the Cleanup Threshold property behavior does not depend on other properties.
* Improved the scene capture cancellation: Users can now cancel the scene capture when the tool is starting up which is better UX since if they picked slow settings they don't intend to reuse, the capture can be cancelled, also, the code is simpler. Changed the behavior of the BakeRC tool properties so that after cancellation the completed captures with the desired settings are enabled. The old behavior where cancellation was documented to restore old results was broken and cannot be made to work unless we store the old results in a separate scene capture but for high capture resolutions that would require a lot of memory. When the SceneCapture is cancelled the channels which were pending and didn't complete are logged in the Output Log in case the user forgets which ones were enabled.
* Simplified the code in various places: Added `operator[](ERenderCaptureType)` to structs with per-capture data, and use it to simplify many places where we previously checked channels individually. Added conversion functions from tool properties/geometry script parameters to the render capture parameters. Removed old confusing logic that determined if a capture had been updated by tracking the number of photos in each photoset with a new system based on a new per-capture pending state. Deprecated a bunch of functions which are no longer useful or which used the wrong types (e.g., `FRenderCaptureUpdate` was added because I hadn't noticed `FRenderCaptureTypeFlags`). Changed the defaults in `FSceneCapturePhotoSet` so that the DeviceDepth capture is off, its an advanced feature and the defaults are intended to make the class friendly to new developers

Add DynamicMeshSelector::UpdateAfterGeometryEdit API. StaticMeshSelector implementation updates static mesh after an Edit instead of emitting MeshChange on temporary DynamicMesh.
Delete and Retriangulate Commands now use this API instead of directly emitting transaction, so now these commands work properly on Static Meshes.
FStaticMeshComponentSelectorFactory::CanBuildForTarget now only allows UStaticMeshComponent specifically, filtering out subclasses. This is not ideal but I don't know what else we can do for now, there are many subclasses like ISMC, SplineMeshComponent, etc, that will not work w/ the Selection system. Also now filtering out Engine assets and cooked assets.
ModelingToolsEditorMode now listens for blueprint pre-compiles, and when this occurs, clears the active selection and selection targets. This is necessary because if the selection Component was part of a BP, on recompile it is re-instanced and the old pointer goes stale. Possibly can handle this better or at a more granular level, but clearing the selection is safest. This currently results in things not being undoable because the FChange transactions are on the "old" UDynamicMesh that no longer exists.
UModelingToolsEditorMode::UpdateSelectionManagerOnEditorSelectionChange now does a more thorough job of inspecting the current Actor/Component selection to find Components that could work w/ the selection system.

This tool mostly encapsulates the basic collision editing behaviors found within the Static Mesh Editor, but exists as a tool within Modeling Mode to work along side existing collision tools, such as Collision to Mesh and Mesh to Collision.
Initial features include:
* Support for selecting and transforming collision primitives, including primitive aware transforms (such as explicit length and radius controls on capsule shapes).
* Adding new simple shapes (spheres, boxes, and capsules)
* Duplicating existing shapes
* Deleting some or all collision geometry

- Fix conversion sometimes making degenerate tris and firing an ensure.
- Fix volume conversion sometimes creating cracks in volumes when dealing with non-convex faces (by deleting necessary colinear verts)
- Make simplification preserve group boundaries when asked.
- Remove colinear verts along group boundaries without losing boundaries when preserving groups.
- Break up faces that have holes into convexes rather than emitting per-triangle faces.
- Make mesh to volume tool use same path for conversion as tool targets, and add controls for preserving groups and simplifying
- Revert to ear clipping if delaunay triangulation fails in converting back from volume

Added a CreateNewActor function to EditorModelingObjectsCreationAPI which finds a factory capable of producing actors of the same type as a provided template actor to create the new actor without needing to create entirely new assets as would have been necessary with the existing functions in EditorModelingObjectsCreationAPI.

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.
