scripted-diff: modernize outdated trait patterns - types

The use of e.g. `std::underlying_type_t<T>` replaces the older `typename std::underlying_type<T>::type`.
The `_t` helper alias template (such as `std::underlying_type_t<T>`) introduced in C++14 offers a cleaner and more concise way to extract the type directly.
See https://en.cppreference.com/w/cpp/types/underlying_type for details.
