[Tensorflow] Fix conv2d_transpose for NHWC layout (#14546)

* [Tensorflow] Fix conv2d_transpose for NHWC layout

If "data_format" == "NHWC", the kernel_layout should be "HWOI" rather than "HWIO".

* remove deed code

* add test cases

* Update test_forward.py

* Update test_forward.py

* Update tensorflow_ops.py

* Update tensorflow_ops.py
