core: Scale filters with "output-extent" role

Browse source 
Some filters such as gegl:spiral have properties which limit
their width and height, separate from the gegl:crop nodes in
GimpDrawableFilter. As a result, they won't scale when the layer
or image is resized even if the crop is updated.

This patch checks if there's a "width" or "height" property with
the "output-extent" role in the filter, and updates those properties
to make sure it resizes correctly. Renders made from selections
are not modified, as the user specifically chose that size.
