Merge "Fixed PHEV expansion in INFO_FUEL_TYPE HAL docs" into main

     *   An FHEV (Fully Hybrid Electric Vehicle) must not include FuelType::FUEL_TYPE_ELECTRIC in

     *   INFO_FUEL_TYPE's INT32_VEC value. So INFO_FUEL_TYPE can be populated as such:

     *     int32Values = { FuelType::FUEL_TYPE_UNLEADED }

     *   On the other hand, a PHEV (Partially Hybrid Electric Vehicle) is plug in rechargeable, and

     *   On the other hand, a PHEV (Plug-in Hybrid Electric Vehicle) is plug in rechargeable, and

     *   hence should include FuelType::FUEL_TYPE_ELECTRIC in INFO_FUEL_TYPE's INT32_VEC value. So

     *   INFO_FUEL_TYPE can be populated as such:

     *     int32Values = { FuelType::FUEL_TYPE_UNLEADED, FuelType::FUEL_TYPE_ELECTRIC }
