ec/lenovo/h8: Implement sticky Fn option.
Useful for accessibility.
Sticky modifier (sticky Fn) is a behaviour of modifier key when
you don't have to hold it pressed to achieve the result. E.g.
with normal Fn brightness up is:
<Press Fn> <Press Home> <Despress Home> <Depress Fn>
With sticky Fn you can do:
<Press Fn> <Depress Fn> <Press Home> <Despress Home>
