power_supply: Add additional USB Type-C properties
Introduce the power_supply_typec_mode enum definitions which
will allow a charger to indicate the type of USB Type-C
connection that is established. Also add additional properties
for indicating CC pin orientation, changing source/sink power
role (useful for dynamic power role swap), and a flag to allow
the charger to expect VBUS changes during USB Power Delivery
power negotiation.
