`jax.jit` now accepts `Layout` instances to the `in_shardings` and `out_shardings` argument. Major changes are just plumbing `in_layouts` and `out_layouts` everywhere. Note that public api is `Layout(device_local_layout, sharding)` which is how users will pass us the Layout but internally we split them apart into device_local_layout and sharding. Docs are coming up on how to use the API and what Layouts mean and how to make sense of them (especially on TPU). PiperOrigin-RevId: 622352537
