Crash in `tf.transpose` with complex inputs

Impact

Passing a complex argument to tf.transpose at the same time as passing conjugate=True argument results in a crash:

import tensorflow as tf
tf.transpose(conjugate=True, a=complex(1))

Patches

We have received a patch for the issue in GitHub commit 1dc6a7ce6e0b3e27a7ae650bfc05b195ca793f88.

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
