[coco] Introduce KernelLayouts.test.cpp (#3006)

* [coco] Introduce KernelLayouts.test.cpp

This commit adds tests for NCHW, NHWC and Generic kernel layouts.

Signed-off-by: Cheongyo Bahk <ch.bahk@samsung.com>
* Reordering header files

* Refactor test name more specifically

* Introduce Generic_at test

* Call both const and non-const Generic::at()
