topology: pre-process-object: add support for updating automatic attributes

Browse source 
Classes definitions in Topology2.0 can have attributes
qualified with the "automatic" constraint. Values for
these attributes will be calculated by the compiler.
This patch provides a generic method for defining automatic
attributes computation logic for different classes.

To update automatic attributes for a class, add an item
in object_build_map with auto_attr_updater defined, and then
add updating logic in the custom auto_attr_updater function.
