Reduce descriptor binding info exposure

Only the descriptor binding type is needed. It's an implementation detail that we currently store the entire original VkDescriptorSetLayoutBinding structures, which might change in the future. This also avoids specializing generated code for things which should not be treated as pipeline immutable state.
