usb: typec: Make bus switch code retimer-aware
Since ports can have retimers associated with them, update the Type-C
alternate mode bus code to also set retimer state when the switch state
is updated.
While we are here, make the typec_retimer_dev_type declaration in the
retimer.h file as extern, so that the header file can be successfully
included in the bus code without redeclaration compilation errors.
