[libc++] Remove _LIBCPP_HIDE_FROM_ABI from <__utility/pair.h> (#196508)

Browse source 
This is a follow-up to #193045. This only drops `_LIBCPP_HIDE_FROM_ABI`
in a small part of the code base to make sure everything works as
expected. Once this has been in trunk for a while and there aren't any
problems, there will be larger follow-up patches to remove
`_LIBCPP_HIDE_FROM_ABI` throughout the code base.
