This change introduces updates to the `tf.XlaCallModule` op in order to support `jax2tf` native serialization. The `tf.XlaCallModule` op contains the StableHLO module, which may involve calling TF host callback functions through `stablehlo.custom_call`. To enable proper functionality, the following modifications were made:

1. The `Pure` trait in the automatically generated `tf.XlaCallModule` op's definition has been replaced with the `MemoryEffects` trait.

2. The `isStateful` flag has been set in the op declaration of `XlaCallModule` to indicate that it has stateful behavior.

3. The TensorFlow side effect analysis has been updated to recursively analyze the TF host callback functions invoked by `tf.XlaCallModule`.

These changes ensure better compatibility and alignment with the `jax2tf` native serialization process, allowing for improved handling of side effects and seamless integration with TensorFlow.
