fix(tvix/eval): don't bubble up io errors from path_exists r/8416
path_exists was returning an error when certain common IO errors were encountered. e.g. in the path "/dev/null/.", path_exists would throw an error because the underlying call to Path::try_exists threw an error because null isn't a directory. But if null isn't a directory, then the path is invalid, so this should really be returning false. That's what nix's behavior is and that's what makes sense. The trait function isn't being changed because some other implementers (e.g. tvix_store_io) have actual errors they can throw.
