Freescape games need a specific iOS control config as default

[neuromancer]

The Freescape games need a specific on-screen configuration in iOS to be, at least, barely playable (e.g move/rotate the player). After some quick experiments, Driller is somehow playable using:

• Show on-screen controller
• Dpad on-screen (instead of thumbstick)
• Minimal gamepad layout
• Pressing any other point of the screen to rotate the camera or move the pointer

Ideally, we should default the control options for this game with the first three options. We should allow the player to disable this, if they want to use keyboard and mouse, but any other alternative will most likely render the game unplayable.

This should be playable after ​https://github.com/scummvm/scummvm/commit/457628ecb8a409ede654fcb9fc886c8b84907fdc. Check in the next TestFlight build.
