libstdc++: Fix handling of common cpp20-only ranges for flat sets [PR119415]
These patch add check to verify if common range iterators satisfies
Cpp17LegacyIterator requirements (__detail::__cpp17_input_iterator),
before invoking overloads of insert that accepts two iterators.
As such overloads existed before c++20 iterators were introduced,
they commonly assume existence of iterator_traits<..>::iterator_category,
and passing a cpp20-only iterators, leads to hard errors.
In case if user-defined container wants to support more efficient
insertion in such cases, it should provided insert_range method,
as in the case of standard containers.

libstdc++-v3/ChangeLog:
* include/std/flat_set (_Flat_set_impl:insert_range):
Add __detail::__cpp17_input_iterator check.
* testsuite/23_containers/flat_multiset/1.cc: New tests
