…_newton_raphson`, and JIT the entire `newton_raphson_solve_block`. The `jax` and `jaxlib` versions are incremented to `0.7` in order to support the new `--xla_backend_extra_options=xla_cpu_flatten_after_fusion` flag, and Python incremented to 3.11 to support jaxlib 0.7.0. This flag treats all functions wrapped with a `jax.jit` within a larger `jax.jit` as independently compilable subfunctions (ie. prevents compiler inlining). It is critical for preventing blowups of compile-times (XLA:CPU compile-times scale roughly quadratically with the number of ops otherwise). Use of jax.lax.custom_root is temporarily disabled until a workaround is found for it significantly increasing compile times. This increases simulation speed by around 20%, but at the cost of ~10% increases in compile-time PiperOrigin-RevId: 795422861
