Use Layout in place of DeviceLocalLayout and .layout in place of .device_local_layout.

JAX is undergoing a rename of the contents of jax.experimental.layouts in preparation for its graduation from experimental:

* "Formats" are replacing "layouts", and specifically `Layout -> Format`
* "Layouts" are replacing "device local layouts", and specifically `DeviceLocalLayout -> Layout`

This is an incremental update carrying out #2.
