Improve completion in IPython/Python 3.13

Browse source 
IPython/Python 3.13 indirectly imports rlcompleter, and the
completer is set up to reference rlcompleter.__main__.
However, this rlcompleter.__main__ is different from the
__main__ in the REPL execution.  Therefore, this completer
cannot correctly complete the REPL globals.  To address this
issue, we override rlcompleter.__main__ with __main__ only in
the case of IPython.

Modify __PYTHON_EL_native_completion_setup().  (Bug#76205)
