    app: replace use of deprecated dont-cache/no_cache with cache-policy
    
    Replace the use of the deprecated GeglNode::dont-cache property,
    and GeglOperationClass::no_cache field, with GeglNode::cache-policy
    and GeglOperationClass::cache_policy, respectively.
    
    See commit gegl@7f24430cda0d8c3eff311868823d445edc2a4e12.
