Resort members of InterfaceInfo to avoid ABI break (backport #3001)

[mergify]

#2997 (comment)

InterfaceInfo is only passed inside a std::vector (its size does not change when the object changes). But the memory layout of the struct changes and accessing it will break. By moving the new member at the end of the struct, this should not be a problem.
