Ignore rasterization state pointers when rasterization is disabled

The Vulkan specification for VkGraphicsPipelineCreateInfo states: * pViewportState is a pointer to a VkPipelineViewportStateCreateInfo structure, and is ignored if the pipeline has rasterization disabled. * pMultisampleState is a pointer to a VkPipelineMultisampleStateCreateInfo structure, and is ignored if the pipeline has rasterization disabled. * pDepthStencilState is a pointer to a VkPipelineDepthStencilStateCreateInfo structure, and is ignored if the pipeline has rasterization disabled or if the subpass of the render pass the pipeline is created against does not use a depth/stencil attachment. * pColorBlendState is a pointer to a VkPipelineColorBlendStateCreateInfo structure, and is ignored if the pipeline has rasterization disabled or if the subpass of the render pass the pipeline is created against does not use any color attachments. Also remove the UNSUPPORTED() for pTessellationState since it is valid for the application to provide a non-null pointer even though tessellation is not supported.
