bpo-43541: Fix PyEval_EvalCodeEx() regression (GH-24918)

Browse source 
* Remove an assertion which required CO_NEWLOCALS and CO_OPTIMIZED
  code flags. It is ok to call this function on a code with these
  flags set.
* Fix reference counting on builtins: remove Py_DECREF().
  Fix regression introduced in the
  commit 46496f9d12.

Add also a comment to document that _PyEval_BuiltinsFromGlobals()
returns a borrowed reference.
