[Enhancement] Hide quests in File Select

[JordanLongstaff]

Closes #5609

This is mostly picking up from where #6634 was before its head repo was dropped. But I also added the logic of skipping over the Quest Select screen. I also migrated the existing CVars related to File Select that were moved into that section of the menu.

Here's a video of the Quest Select screen being skipped to start the only mode available (with text indicating which mode):

And in this video, the only one hidden is Normal, so Quest Select is shown but only has Rando and Boss Rush.

Not a fan of the implementation for the text, the most logical thing would to make something like COPY / ERASE when you try to copy / erase an empty file
If you need custom texture to mimics those and display them next to the file number when hovering, just ask

This PR has nothing to do with that text. Besides, those are just the textures from the game.
