libcamera: camera_sensor: Initialize PixelArray properties
Initialize pixel array properties 'PixelArraySize' and 'PixelArrayActiveAreas' by inspecting the V4L2 CROP_BOUNDS and CROP_DEFAULT selection targets. The properties are registered only if the sensor subdevice support the above mentioned selection targets.
