Add option to override controller button look

[hl2jeep]

I'm playing on a steam deck hooked up to a TV with a ps5 controller and I'm finding it a bit annoying that the button hints are for the steam deck layout, there is no option to override the controller type at all Also my PS5 controller gets detected as a steam deck controller. And beta 2.0.0 completely doesnt detect controllers on 1.20.1 for me so I'm using beta 1.7.0
