[CK_TILE] Pooling FWD (Lwpck 3683) (#2956)

* Pooling 2D/3D with refernce

* Tests & cleanup

- added test for ppoling
- cleanup
- removed 2d example

* Comment resolution

- README added
- example target name rectified
- appropriate arg description and comments added

* clang-format

* appropriate blocksize calc

* modifications for future indexing addition

- instead of transforming views we now transform the descriptors, so
that the same descriptor can be re-used for index tensor in the future

* some basic fixes

* comment resolutions

* comment resolutions
