Expands a shortcut label into an object with the label and a corresponding ARIA key shortcuts value.
Could handle "CtrlOrCmd" like Electron does, here, or just treat "Ctrl" as control or command.
Of course it would be more ergonomic if OS-GUI.js handled this sort of thing,
and I have thought about rewriting the OS-GUI API to mimic Electron's.
I also have some munging logic in electron-main.js related to this.
@param {string} shortcutLabel
@returns {{shortcutLabel?: string, ariaKeyShortcuts?: string}}
