The reason for the CPU option is to say: never use my GPU, even if
it's enabled in the scene (e.g. because it's too weak). If each GPU
gets a toggle to turn it on/off the CPU option indeed is not needed

What we could have is an option to toggle usage of the CPU in addition
to the GPUs, but that will some deeper internal changes before it
