`CHECK` fail in `BCast` overflow

Impact

If [BCast::ToShape](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/util/bcast.h) is given input larger than an int32, it will crash, despite being supposed to handle up to an int64. An example can be seen in [tf.experimental.numpy.outer](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/util/bcast.h) by passing in large input to the input b.

```python

import tensorflow as tf

value = tf.constant(shape=[2, 1024, 1024, 1024], value=False)

tf.experimental.numpy.outer(a=6,b=value)

`

Patches

We have patched the issue in GitHub commit [8310bf8dd188ff780e7fc53245058215a05bdbe5](https://github.com/tensorflow/tensorflow/commit/8310bf8dd188ff780e7fc53245058215a05bdbe5).

The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
