  -----------
  [libc++] Make std::pair trivially copyable if its members are (#89652)

This makes `std::pair` trivially copyable if its members are and we have
a way to do so. We need either C++20 with requires clauses or support
for `__attribute__((enable_if))`. Only Clang has support for this
attribute, so it's effectively clang or C++20.
