libcamera: camera_sensor: Add frame length limits to CameraSensorInfo
Sensor frame length is made up of active and inactive (blanking) lines. The minimum and maximum frame length values may be used by pipeline handlers to limit frame durations based on the sensor mode capabilities. Store the minimum and maximum allowable frame length values (in lines) in the CameraSensorInfo structure. These values are computed in CameraSensor::sensorInfo() by querying the sensor subdevice V4L2_CID_VBLANK control limits. This in turn means that V4L2_CID_VBLANK is now a mandatory subdevice control.
