Nikolas Klauser 3583bf3ad8 [libc++] Make everything in namespace std have default type visibility and hidden visibility and remove _LIBCPP_ENUM_VIS
This avoids having to add `_LIBCPP_ENUM_VIS`, since that is handled through `type_visibility` and GCC always makes the visibility of enums default. It also fixes and missing `_LIBCPP_EXPORTED_FROM_ABI` on classes when using Clang.
