Add support for a 5th modifier key called "hyper", this is a modifier supported on Wayland & X11 although other platforms could support an additional modifier too. Both GNOME and KDE can map CapsLock to Hyper. Other compositors can use the XKB_DEFAULT_OPTIONS environment variable. This allows users to have an additional modifier for their own use that doesn't conflict with other keys. Ref !136340
