bindings: prepare for more modifers

Prepare to support more modifiers in key bindings.

tcell has some premade ctrl-modified keys but not all keys are
supported. Other keys must be explicitly checked with a modifier mask.

Update the KeyStroke type to carry a modifier mask. Update code
accordingly.

No functional change.
