IVGCVSW-3738 Add end-to-end layer test for DepthToSpace

* Added end-to-end layer test implementation for DepthToSpace
* Added test to reference, CL and NEON backends for all supported
  data types and data layouts
* Extracted common data permutation code into new utility file and
  refactored some existing tests to reduce code duplication
* Fixed EndToEndLayerTestImpl template to work with Float16 data
