Niels Lohmann 5b11a0282c Exchange the CustomBaseClass subobject in basic_json::swap() (#5697 )

basic_json::swap() (and the friend swap() and the pre-C++20 std::swap
overload that forward to it) only exchanged m_data.m_type/m_data.m_value,
leaving each value's json_base_class_t subobject in place. This is
inconsistent with the copy and move constructors and copy assignment,
which all carry the base class along with the value, so after
a.swap(b) any metadata stored in a CustomBaseClass ended up attached to
the wrong value. Algorithms that mix swap() with moves, such as
std::sort, scrambled the metadata across the whole container.

Fix the member swap() to also exchange the json_base_class_t subobject
and extend the noexcept specifications of swap() and the friend swap()
accordingly.

Fixes #5653.
