Fix extra bottom margin when navbar buttons absent (#1024)

Browse Source 
* Fix extra bottom margin when navbar buttons absent

Fix the extra space that was appearing when the gesture-navigation bar
didn't contain the "switch IME" or "close IME" buttons.
This was found on OneUI 7 with the two "keyboard key" related options
turned off.

* Remove unneeded nav bar detection and width computation
