PYSEC-2026-973

### Impact The function `tf.raw_ops.LookupTableImportV2` cannot handle scalars in the `values` parameter and gives an NPE.

```python import tensorflow as tf

v = tf.Variable(1)

@tf.function(jit_compile=True) def test(): func = tf.raw_ops.LookupTableImportV2 para={'table_handle': v.handle,'keys': [62.98910140991211, 94.36528015136719], 'values': -919}

y = func(**para) return y

print(test()) ```

### Patches We have patched the issue in GitHub commit [980b22536abcbbe1b4a5642fc940af33d8c19b69](https://github.com/tensorflow/tensorflow/commit/980b22536abcbbe1b4a5642fc940af33d8c19b69).

The fix will be included in TensorFlow 2.12. We will also cherrypick this commit on TensorFlow 2.11.1.
