Describe the bug
Normally test data for convolution is in format:

• [N, C, H, W] or [N, H, W, C] for 2D
• [N, C, D, H, W] or [N, D, H, W, C] for 3D
  but in these tests: https://github.com/Microsoft/onnxruntime/blob/master/onnxruntime/test/providers/cpu/nn/conv_transpose_op_test.cc#L394-L474
  data shape rank is 4 for both 2D and 3D tests.
  3D and 2D tests differ only in rank of strides and amount of pads dimensions which seems invalid.

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Ubuntu 16.04.6 LTS
• ONNX Runtime installed from (source or binary): source
• ONNX Runtime version: master
• Python version: n/a
• GCC/Compiler version (if compiling from source): 5.4.0
• CUDA/cuDNN version: n/a
• GPU model and memory: n/a

Expected behavior
Expect test to pass using different data shapes.
