Niels Lohmann 03d3bc352e Make diff_frame a member struct that declares its special members ...

GCC's -Weffc++ (an error in CI) asks a class with pointer members, a
user constructor and a non-trivial destructor to declare its copy
constructor and copy assignment; diff_frame's vector and basic_json
members make its destructor non-trivial. Declare all five as defaulted,
which also satisfies clang-tidy's special-member-functions check. Leave
their exception specifications implicit: GCC 4.8 rejects an explicit
one that differs from the implicit one, as it does for flatten_task in
#5517.

The converting constructor cannot throw, and is now declared noexcept
for GCC's -Wnoexcept, which flags the emplace_back() under C++26
otherwise. The struct also moves from diff_iteratively() into the class,
like dump_frame in the serializer.
