platform/x86: asus-wmi: add safety checks to gpu switching

Browse source

Add safety checking to dgpu_disable, egpu_enable, gpu_mux_mode.

These checks prevent users from doing such things as:
- disabling the dGPU while is muxed to drive the internal screen
- enabling the eGPU which also disables the dGPU, while muxed to
  the internal screen
- switching the MUX to dGPU while the dGPU is disabled
