This CL extracts weak object worklist related code into separate files
and uses a macro to specify all weak object worklists in a generic way.

The motivation of the refactoring is twofold:
1) We can now enforce that each weak object worklist is updated after
   Scavenge. (Forgetting to define the update function causes a link
   time error.)
2) The reduced boilerplate will be useful for transitioning to the
   new ::heap::base::Worklist.
