usb: typec: Add data structure for Enter_USB message

Browse source 
This data structure can be delivered to the mux drivers when
Enter_USB Message is used exactly the same way as the
Alternate Mode specific data structures are delivered to the
mux drivers when Enter Mode Messages are used.

The Enter_USB data structure shall have all details related
to the Enter_USB Message, most importantly the Enter_USB
Date Object that was used.
