Tidy up use of FPrimitiveSceneProxy velocity getters.
Now DrawsVelocity() is only for velocity relevance.
And HasDynamicTransform() is for determining if we need to store previous transform state.
VSM caching was using PRIMITIVE_SCENE_DATA_FLAG_DRAWS_VELOCITY so replaced that with PRIMITIVE_SCENE_DATA_FLAG_SHOULD_CACHE_SHADOW which should use the old behavior and can be tweaked in future using ShouldCacheShadow().
A common pattern for determining whether to output velocity now is to check if a previous transform exists, and to OR in AlwaysHasVelocity().
I found some proxy types that don't check for previous transform.
Also I found that the debug physics aggregate types *never* check for previous transform.
These are pre-existing potential bugs for fixing in another pass.
Also I found some proxies that don't currently fill out velocity relevance.
These are pre-existing potential bugs for fixing in another pass.

To support this, adds an AggGeom to the dynamic mesh component, which collision update functions should update instead of the one on the current BodySetup. This ensures new collision changes are not overwritten by an async build replacing the BodySetup.

UDynamicMesh: Add a bEnforceAttributeInvariants flag to the EditMesh function. If it's false, don't try to enable all required mesh attributes after the edit occurs.
Modify the DiscardMeshAttributes function in Geometry Script to not enforce attribute invariants -- otherwise the function does nothing.

- add DynamicMeshComponent::SetComplexAsSimpleCollisionEnabled(), SetDeferredCollisionUpdatesEnabled() to handle some common component variable configuration in BP.
- expose DynamicMeshComponent::UpdateCollision()
GeometryScripting:
- pass UDynamicMesh TargetMesh as parameter to GeneratedDynamicMeshActor::OnRebuildGeneratedMesh(), to simplify BPs and leave open the possibility of updating a compute mesh separate from the actual Component mesh
- Automatically enable (then disable) deferred collision updates on DynamicMeshComponent in AGeneratedDynamicMeshActor::ExecuteRebuildGeneratedMeshIfPending, otherwise every GeometryScript node will rebuild collision (!)

Also do some refactoring to pass settings structs which improve readability when setting options, reduce the need to change call sites due to signature changes, and allow overloading of Read/Load functions which return some type

[CL 17794212 by aurel cordonnier in ue5-release-engine-test branch]
- add FRayTracingGeometry structures to FMeshRenderBufferSet for primary and secondary triangle indices
- add UpdateRaytracingGeometryIfEnabled() function which rebuilds these raytracing data structures. This does a full rebuild, not clear if any kind of incremental update is possible currently, to revisit in future.
- call the above in the various places where we modify the existing index/vertex buffers.
- add UPrimitiveComponent::GetDynamicRayTracingInstances() implementation, mirrors GetDynamicMeshElements() implementation, uses new DrawRayTracingBatch() function

- UDynamicMesh Reset() functions now return themselves, configured as BP output pin, helps to make BP wiring cleaner
- added DynamicMeshComponent::ConfigureMaterialSet() and ::ValidateMaterials(), to allow material set to be updated from BP
- added BaseDynamicMeshComponent::SetNumMaterials() to support above
