Set battery charge custom stop charging in percent

If DeviceBatteryChargeMode is set to "custom", then setting DeviceBatteryChargeCustomStopCharging customizes when the battery stops charging, based on the percentage of battery charge. DeviceBatteryChargeCustomStartCharging must be at least 5 percentage points below DeviceBatteryChargeCustomStopCharging.

Leaving the policy unset applies the "standard" battery charge mode.
