USB Mux: Set an event when AP mux sets complete
The AP will need to know when its selected mux has finished setting.
For now, most boards have at most one mux and one retimer, and so add
events for each of those.
BRANCH=None
BUG=b:208882941,b:155889939
TEST=on nipperkin, set muxes via the AP console and view the
corresponding events are set
