Affected: PyPI: tensorflow, PyPI: tensorflow-cpu, PyPI: tensorflow-gpu

### 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()) ```
