Note the dependency change introduced by `VkInputAttachmentAspectRefernceKHR` is not handled yet. Following Note and TODO added as comments The intput attachment aspect info is only cached but not used for now, so the dependency can be wrong as a draw call may depends on just one aspect of a depth stencil image, as specified in the input attachment aspect info, while GAPID will still treat both aspects as dependees. TODO: Once the CL that enables us getting used descriptors from shader is in, we can pull `input_attachment_index` from the information of the used descriptors then use the input attachment aspect info to fix the dependency.
