// A Helper type used to build a pNext chain of extension structs.
// Usage is:
//   1) Create instance, passing the address of the first struct in the chain. This requires
//      pNext to be nullptr. If you already have a chain you need to pass a pointer to the tail
//      of it.
//
//   2) Call Add(&vk_struct) every time a new struct needs to be appended to the chain.
//
//   3) Alternatively, call Add(&vk_struct, VK_STRUCTURE_TYPE_XXX) to initialize the struct
//      with a given VkStructureType value while appending it to the chain.
//
// Examples:
//     VkPhysicalFeatures2 features2 = {
//       .sType = VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FEATURES_2,
//       .pNext = nullptr,
//     };
//
//     PNextChainBuilder featuresChain(&features2);
//
//     featuresChain.Add(&featuresExtensions.subgroupSizeControl,
//                       VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBGROUP_SIZE_CONTROL_FEATURES_EXT);
//
// Note:
//   The build option `use_asan_unowned_ptr` checks the pointer to the current
//   tail it is not dangling. So every structs in the chain must be declared
//   before `PNextChainBuilder`.
