Brian Ashworth 55e1d599a2 input_cmd_events: implement toggle
Implements toggling input events during runtime. This will not attempt
to toggle to a mode that is not supported by the device.

When toggling the wildcard input, the device specific input configs are
altered. Each device will cycle one supported mode.
