After python#14063, calls to `psutil.process_iter` and `psutil.Process.as_dict` are being reported by Pyright, as the `ad_value` parameter is untyped. However, given that (from the documentation) this is just a placeholder value to use when an error is raised while fetching some attribute, I think that typing it as `object` is appropriate.

Considering that the supplied type influenced the result type (but we can't express that relation properly), Any is a bit more appropriate. Also, we need to document uses of Any, see suggestions below.
