Add support for calling typec_set_mode() for the DEBUG, AUDIO
accessory modes.
Let's also call typec_set_mode() for USB as default and SAFE
when partner is disconnected.
The USB state is only called when ALT mode is specifically
not specified by the partner status flags in order
to leave the altmode handlers setup the proper mode to
switches, muxes and retimers.
