Move object runtime data to a separate header and allocate it separately as `blender::bke::ObjectRuntime`. This is how node, mesh, curves, and point cloud runtime data is stored. Benefits: - Allow using C++ types in object runtime data - Reduce space required for Object struct in files - Increase conceptual separation between DNA and runtime data - Remove the need to add manual padding in runtime data - Include runtime struct definition only in files that require it Pull Request: https://projects.blender.org/blender/blender/pulls/113957
