[3.11] gh-103578: Fix pdb reading code with non-utf8 encoding (GH-103581) (#103867)

Fixed a bug where :mod:`pdb` crashes when reading source file with different encoding by replacing :func:`io.open` with :func:`io.open_code`. The new method would also call into the hook set by :func:`PyFile_SetOpenCodeHook`.
