[libcxx-commits] [libcxx] [libc++][filesystem] Report an error for canonical("") (PR #215031)

How do other implementations handle this? Do they report an error in `weakly_canonical`, or also return the current directory? I feel like we might want to have these two consistent in this specific case.
