Mainmenu: Clean up and improve advanced settings dialogues (#7802)
Improvements: 1. Formspec size and description box are calculated last 2. Width and height are now adjustable per setting type 3. Error message (dialogdata.error_message) shortens the description field and is placed below 4. Add more spacing for larger fonts 5. More comments and extensible by setting different height and width values
