- Deprecated FRayTracingMeshResourceCollector and FRayTracingMaterialGatheringContext.
- Instead GetDynamicRayTracingInstances(...) implementations should use the new FRayTracingInstanceCollector which extends FMeshElementCollector with ray tracing functionality (AddRayTracingInstance/AddReferencedGeometryGroup/AddRayTracingGeometryUpdate)
- this is similar to GetDynamicMeshElements(...) using FMeshElementCollector.
- FRayTracingInstanceCollector uses a dedicated RHI command list to gather instances, which is different than FRayTracingMaterialGatheringContext which used the immediate command list.
- Moved dynamic instance gathering logic in RayTracing.cpp into a new class FDynamicRayTracingInstancesContext laying the foundation of gathering dynamic instances in parallel threads on follow up changes.
