libcamera: controls: Define a default lens position behaviour

Browse source 
Update the AfMode control description to explicitly define a
startup/default behaviour.

On startup, the camera will move the lens to the position given by the
default value of the LensPosition control if operating in manual focus
mode. Typically this would be the hyperfocal position of the lens.
