Prevent Pipeline crashing on missing non mandatory structures

When constructing a Graphics pipeline, some structures may or may not exist, depending on what will be used by the render pass. These structures (viewportState, multisampleState, depthStencilState and colorBlendState) are now checked before being used, since it is allowed for these to be null.
