Allocator-extended constructors for container adaptors.
PR libstdc++/65092
* include/bits/stl_queue.h (queue, priority_queue): Add
allocator-extended constructors.
* include/bits/stl_stack.h (stack): Likewise.
* testsuite/23_containers/priority_queue/requirements/
uses_allocator.cc: Test allocator-extended constructors.
* testsuite/23_containers/queue/requirements/uses_allocator.cc:
Likewise.
* testsuite/23_containers/stack/requirements/uses_allocator.cc:
Likewise.
