Feature Request - Add missing disable callback functions

[weilbith]

Hey 👋🏾

First of all, I love this plugin. Thank you very much for all the hard work! 🙏🏾

There is this nice setup option disable_winbar_cb to conditionally disable the window bar with custom code. I would love to see such functions for the other "things" too. In my current case, specifically for the statuscolumn. Not sure if it makes sense for the tabline and statusline too, but would be quite complete if so.
What do you think?
