common/usbc: Allow boards to determine DTS (CCD) port
This adds support for a board specific function to determine if a
particular port supports DTS (Debug and Test System) - more commonly
known as the CCD port. Typically, only one port supports CCD and we
should not enter debug accessory mode on non-CCD ports.
The default implementation simply returns true which is equivalent to
the original behavior. Boards can override board_is_dts_port() to limit
entering debug accessory mode to specific ports.
