Issue #27213: Fixed different issues with reworked CALL_FUNCTION* opcodes.

* BUILD_TUPLE_UNPACK and BUILD_MAP_UNPACK_WITH_CALL no longer generated with
  single tuple or dict.
* Restored more informative error messages for incorrect var-positional and
  var-keyword arguments.
* Removed code duplications in _PyEval_EvalCodeWithName().
* Removed redundant runtime checks and parameters in _PyStack_AsDict().
* Added a workaround and enabled previously disabled test in test_traceback.
* Removed dead code from the dis module.
