Implement C++20 constexpr changes to std::pair (P1032R1)

* include/bits/stl_pair.h (pair): Add _GLIBCXX20_CONSTEXPR to
piecewise construction constructor, assignment operators, and swap.
* include/std/tuple (pair::pair(piecewise_construct_t, tuple, tuple)):
Add _GLIBCXX20_CONSTEXPR.
(pair::pair(tuple, tuple, _Index_tuple, _Index_tuple)): Likewise.
* testsuite/20_util/pair/constexpr_assign.cc: New test.
* testsuite/20_util/pair/constexpr_swap.cc: New test.
