With dynamic rendering the API formally eliminates render passes,
so the pipeline create info can now have a NULL render pass, in
which case rendering info must be provided via pNext struct
VkPipelineRenderingCreateInfo, or if this is missing too then
defaults to no multiview and no attachments.
Since we don't want to have separate paths all over the place
whenever we need to access render pass / rendering info for the
pipeline, we will always produce a valid vk_render_pass_state
struct with the relevant information even when we have a render
pass, so we can rely on that always being available.
A follow-up patch will rewrite all the places where we assumed
the existence of a render pass in the pipeline to instead fetch
the info it needs from this new field instead.
