FPE in `tf.image.generate_bounding_box_proposals`

Impact

When running on GPU, tf.image.generate_bounding_box_proposals receives a scores input that must be of rank 4 but is not checked.

import tensorflow as tf

a = tf.constant(value=[[1.0, 1.0], [1.0, 1.0], [1.0, 1.0], [1.0, 1.0]])
b = tf.constant(value=[1])

tf.image.generate_bounding_box_proposals(scores=a,bbox_deltas=a,image_info=a,anchors=a,pre_nms_topn=b)

Patches

We have patched the issue in GitHub commit cf35502463a88ca7185a99daa7031df60b3c1c98.

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.
