usb_mux: Add support for host-controlled 'virtual' USB mux
For designs where the host SOC is responsible for setting the USB-C SS
mux, the EC must track the desired mux state and inform the host when
the desired state changes. Then, the host must ask the EC for the new
desired state and set the mux accordingly.

Attach USB dongle in port 1 and DP dongle in port 0, then verify `ectool
