per P1425R4.
(queue(InputIterator, InputIterator)): Likewise.
(queue(InputIterator, InputIterator, const Alloc&)): Likewise.

Define.
* testsuite/23_containers/queue/cons_from_iters.cc: New test.
* testsuite/23_containers/stack/cons_from_iters.cc: New test.
I forgot to update the patch to use the final value of the feature
test macro. It should be 202106L.
Tested powerpc64le-linux. Committed to trunk.

libstdc++: Update __cpp_lib_adaptor_iterator_pair_constructor value
I started implementing this feature before it was voted into the C++ WP,
and forgot to update the feature test macro after it was approved.
This defines it to the correct value, as specified in the C++23 draft.
libstdc++-v3/ChangeLog:
* include/bits/stl_queue.h
(__cpp_lib_adaptor_iterator_pair_constructor): Set to correct
value.
* include/bits/stl_stack.h
(__cpp_lib_adaptor_iterator_pair_constructor): Likewise.
* include/std/version
(__cpp_lib_adaptor_iterator_pair_constructor): Likewise.
* testsuite/23_containers/queue/cons_from_iters.cc: Update
expected value.
* testsuite/23_containers/stack/cons_from_iters.cc: Likewise.
