libcamera: camera_sensor_properties: Add sensor control delays

Browse source 
Add properties covering the sensor control application delays to both
the static CameraSensorProperties definitions. The values used are
taken from Raspberry Pi's CamHelper class definitions. Where no more
specific values are known the delay struct is defined as empty and
defaults supplied through the getter function.
