We've started using `_LIBCPP_BEGIN_NAMESPACE_STD` and `_LIBCPP_END_NAMESPACE_STD` for more than just the namespace for a while now. For example, we're using it to add visibility annotations to types. This works very well and avoids a bunch of annotations, but doesn't work for the few places where we have an unversioned namespace. This adds `_LIBCPP_BEGIN_UNVERSIONED_NAMESPACE_STD` and `_LIBCPP_END_UNVERSIONED_NAMESPACE_STD` to make it simpler to add new annotations consistently across the library as well as making it more explicit that the unversioned namespace is indeed intended.
