[power-udev] Handle high voltage dedicated chargers. Fixes JB#39319

When high voltage charger is connected, initially kernel reports
USB_DCP and then switches to USB_HVDCP. As the high voltage
dedicated charger profile types are not known to statefs and
the value of OnBattery property is derived from the charger type,
the observers of statefs properties see what looks like a charger
connect followed almost immediately by charger disconnect.

When kernel reports either USB_HVDCP or USB_HVDCP_3 charger type,
expose it as "hvdcp" charger type from statefs udev provider.
