Niels Lohmann a0fe86d087 Fix stale #include lines in the output headers ...

output_adapters.hpp included <algorithm> and <iterator> for std::copy
and std::back_inserter, which have not been used there since #3569
(2022). serializer.hpp included <algorithm> for std::reverse (also
unused), <cmath> for labs/isnan/signbit (only std::isfinite is used)
and <utility> for std::move (nothing from <utility> is used there),
while using std::next without including <iterator> at all, relying on
getting it transitively through output_adapters.hpp's own stale
<iterator>.

Drop the unused includes, add <iterator> for std::next, and correct
the remaining include comments. Both headers still compile standalone
with -Wall -Wextra -Werror.

Part of #5709
