This PR fixes the issue noted in https://github.com/pydata/xarray/issues/7493#issuecomment-1953091000 that non-nanosecond precision datetime or timedelta values passed to expand_dims would not be cast to nanosecond precision. The underlying issue was that the _possibly_convert_datetime_or_timedelta_index function did not appropriately handle being passed PandasIndexingAdapter objects.
