  Changed paths:
    M libcxx/include/__config
    M libcxx/include/__utility/forward.h
    M libcxx/include/__utility/forward_like.h
    M libcxx/include/__utility/move.h
    A libcxx/test/libcxx/utilities/utility/forward/lifetimebound.verify.cpp

  Log Message:
  -----------
  [libc++] Add [[clang::lifetimebound]] attribute to std::forward and friends

This allows clang to catch lifetime bugs through these functions.
As a drive-by, replace `_LIBCPP_INLINE_VISIBILITY` with `_LIBCPP_HIDE_FROM_ABI`.
Fixes #59900
