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.
