Resolve logical partition specs to physical mesh axes for optimizer and model states during sharding. Apply sharding constraints to gradients matching model partitioning, and replicate denominator. Add filter_spec utility to filter out axes from PartitionSpec that are not present in the mesh. PiperOrigin-RevId: 955964815
