Regression causing eq/ne_missing to incorrectly give NULL when comparing NULLs instead of True/False

Fixes #19153

Adds

  • test_eq_lists_arrays for == / !=
  • test_eq_missing_lists_arrays_19153 for eq_missing / ne_missing

Tests are parametrized to test both lists and arrays

I agree with the bug fix but the test adjustments I am not sure about.
