refs: rename 'pack_refs_opts' to 'refs_optimize_opts'

The previous commit removed all references to 'pack_refs()' within
the refs subsystem. Continue this cleanup by also renaming
'pack_refs_opts' to 'refs_optimize_opts' and the respective flags
accordingly. Keeping the naming consistent will make the code easier to
maintain.
