libstdc++: Make copyable-box completely constexpr (LWG 3572)

This LWG issue was approved at the October 2021 plenary and can be
implemented now that std::optional is fully constexpr.

libstdc++-v3/ChangeLog:

* include/std/ranges (ranges::__detail::__box): Add constexpr to
assignment operators (LWG 3572).
* testsuite/std/ranges/adaptors/filter.cc: Check assignment of a
view that uses copyable-box.
