Code samples: add CMakeLists.txt

Calling `cmake --build .` will build the sample code executables for each
chapter in it's own folders, compile corresponding shaders and copy all
required resources to appropriate sub-folders. After that any example is
ready to be run from it's build sub-folder.

CMake project requires following dependencies:
* glfw3 dev package
* glm dev package
* stb_image header
* tinyobjloader dev package
* Vulkan sdk
