Delay the creation of the `prim_map` data structure until the last possible moment. This is more efficient in the majority of cases where no Import hooks have been defined. Additionally, it removes the need for locking in the `read_object_data` code path once we implement concurrent loading. Pull Request: https://projects.blender.org/blender/blender/pulls/132360
