fix Poly.diff to address Make .diff() call convention for high derivatives - consistent across the codebase #1029 and Poly.diff() doesn't support higher order derivatives sympy/sympy#19590
release notes

This now follows Mathematica D[] call convention (or Maple's diff). Support for differentiation of symbolic order (see diofant#1066) also would require that change. More simple testing in test_diff_args(). Closes sympy/sympy#19590 Closes diofant#1029
