Improve suggestion in NameError when deleting builtins

Bug report

Bug description:

When deleting a name, python will only find the name in globals and locals, no builtins. However, the suggestion generating code just combined these dict, which makes the suggestion cycle:

>>> del next
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    del next
        ^^^^
NameError: name 'next' is not defined. Did you mean: 'anext'?
>>> del anext
Traceback (most recent call last):
  File "<python-input-1>", line 1, in <module>
    del anext
        ^^^^^
NameError: name 'anext' is not defined. Did you mean: 'next'?

According to DPO, the best way to fix this bug is using dis to analyse the last traceback to get the final operation.

Reproduza o problema com del next e del anext, depois inspecione o caminho de geração de sugestões de NameError e use dis para identificar a operação final a partir do traceback. Compare a abordagem com o PR vinculado gh-141389; considera-se concluído quando a exclusão não sugerir mais o builtin excluído como alternativa.
