[libc++] Reintroduce the removed std::char_traits specialization (#66153)
This partially reverts commit e30a148b098, which removed the base
template for std::char_traits. That base template had been marked as
deprecated since LLVM 16 and we were planning to remove it in LLVM 18.
However, as explained in the post-commit comments in
https://reviews.llvm.org/D157058, the deprecation mechanism didn't work
as expected. Basically, the deprecation warnings were never shown to
users since libc++ headers are system headers and Clang doesn't show
warnings in system headers.
As a result, this removal came with basically no lead time as far as
users are concerned, which is a poor experience. For this reason, I am
re-introducing the deprecated char_traits specialization until we have a
proper way of phasing it out in a way that is not a surprise for users.
