*Added FPrimitiveSceneDesc, a structure you can initialize with a description of the primitive you're trying to Add/Remove/Update in the FScene
-Added entry points in FSceneInterface to do those operations, legacy entry points using UPrimitiveComponent are untouched.
-The code that executes those operations in FScene has been refactored to be shared between the two entry points as much as possible to lessen the additional maintenance burden.
*Added FPrimitiveSceneProxyDesc/FStaticMeshSceneProxyDesc/FInstancedStaticMeshSceneProxyDesc, structures that hold all the necessary information to create a FPrimitiveSceneProxy/FStaticMeshSceneProxy/FInstancedStaticMeshSceneProxy without depending on AActors or UPrimitiveComponent.
-Those structures can be initialized by constructing them with the corresponding UPrimitiveComponents, or by constructing their default versions and initializing the desired fields.
-Creation code for FPrimitiveSceneProxy/FStaticMeshSceneProxy/FInstancedStaticMeshSceneProxy now takes all its info from those desc structures. They are created on demand during scene proxy creation for UPrimitiveComponents. This means no additional memory, and all serialized assets & blueprints are unaffected.
*Added IPrimitiveComponent/IStaticMeshComponent interfaces
-These allow for some editor-only interactions occurring during proxy creation, and serve as a common interface for some code that expected to manipulate UPrimitiveComponent/UStaticMeshComponents. For example FObjectCacheEventSink / FObjectCacheContext now uses those interfaces to associate the resources between various users and interactions like proxy recreation on shader/mesh changes occur through those interfaces.
* Misc
-Moved scene primitive related member variables into a new structure (FPrimitiveSceneInfoData) to facilitate code sharing and implementations of various related functionality (like SetLastRenderTime).
-Changed ObjectCacheContext to store associations between resources and components using component interfaces so that other systems creating proxies have the proper behaviors when resource changes require proxy recreation.
-Added natvis support so that component interfaces to UPrimitiveComponent/UStaticMeshComponent display the component ptr for easier debugging.
-Changed FMotionVectorSimulation to use UObject* instead of UPrimitiveComponent*, it was already using this internally
-Templatized some nanite helpers like ShouldCreateNaniteProxy & AuditMaterials since we need to use them from both UPrimitiveComponent & FPrimitiveSceneProxyDesc and it'll help make sure we keep them in sync.

* 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.
