Fix IndexError in crosstab with aggfunc=‘skew’.

  • Check if table is empty before accessing last row in _normalize function in pandas/core/reshape/pivot.py.
  • Skip normalization and return empty table if it is.
  • Add test case in pandas/tests/reshape/test_crosstab.py for aggfunc=‘skew’.
  • Ensure test case doesn’t raise IndexError.
