Apple keyboard cursor keys don't work, accessibility bar covers bottom of screen

[Purduecoz]

This issue seems to be similar to previous keyboard issues with the iOS port.

I built ScummVM stable (2.3.0pre) and master and installed them onto the GM/RC of iPadOS/iOS 15. Using the Apple Magic keyboard causes an accessibility bar to cover the bottom inch or so of the screen, which affects most games that don't have a parser/input bar at the bottom (it is only just barely below the parser line for the AGI engine, and with the SCI engine, it covers the bottom of the screen). There is a minimize option accessible from the bar that minimizes it to a button in the lower right corner which helps greatly.

The bigger problem is that the left/right/up/down arrow keys do not work, nor do Control modified keys (like Control-Q to quit in the SCI engine). Letters, numbers, and return seem to work fine.
