Requiring PreviousGlobalTransform for MeshletMesh is probably wrong #18784
Description
The first frame an entity is spawned, PreviousGlobalTransform should equal the current GlobalTransform. However, it'll be whatever the default is for PreviousGlobalTransform due to required transforms.
Also in extract_meshlet_mesh_entities, there's no need to use Option<&PreviousGlobalTransform>.
