It checks for global-key-binding every time when the user types C-TAB.
So it could also check with local-key-binding and
minor-mode-key-binding in e.g. outline mode, etc.

But since you want to move the C-TAB keybinding from tab-bar-mode-map
back to tab-bar--define-keys, then :filter is not needed anymore,
so you can check for global-key-binding only once in tab-bar--define-keys.
