Description: Uses a better hashing algorithm to get better dispersion and remove commutativity. Incorporates co_firstlineno, Py_SIZE(co), and bytecode instructions. This is now the entire set of criteria used in code_richcompare, except for _PyCode_ConstantKey, which incorporates the types of co_consts rather than just their values. Issue: gh-94155
