Change cooked_index_worker to abstract base class

This changes cooked_index_worker to be an abstract base class.  The
base class implementation is moved to cooked-index.c, and a concrete
subclass is added to read.c.

This change is preparation for the new .debug_names reader, which will
supply its own concrete implementation of the worker.
