[education/labplot] src/backend/script/python: [scripting] filter out Qt/QObject internal methods that shouldn't be part of the public API

Git commit 7da01eae0bf111253cbc5f5198c3eaaa4157ba66 by Alexander Semke.
Committed on 01/08/2026 at 20:22.
Pushed by asemke into branch 'master'.

[scripting] filter out Qt/QObject internal methods that shouldn't be part of the public API
shown in the completion box. For now, the user still will be able to call them, 
but they won't be suggested in the completion box. Later we'll need to decide if we want to
remove them from the public API completely by filtering them out in the shiboken binding generation.
