Finally, [*Boost.Container]'s polymorphic resource library includes support for
dynamic memory allocation for over-aligned types (introduced in C++17), in older

* Implemented C++20's [funcref boost::container::uninitialized_construct_using_allocator uninitialized_construct_using_allocator]
and [funcref boost::container::make_obj_using_allocator make_obj_using_allocator].
* Added `[[nodiscard]]` to several allocator and PMR utilities.
* Implemented overaligned operator new/delete support for `new_allocator` and `pmr::new_delete_resource()`:
* Uses C++17's `cpp_aligned_new` if available.
* Uses alternative aligned allocation functions for Win32/Unix otherwise.
