[PATCH v5 21/34] merge-recursive: make a helper function for cleanup for handle_renames

In anticipation of more involved cleanup to come, make a helper function for doing the cleanup at the end of handle_renames. Rename the already existing cleanup_rename[s]() to final_cleanup_rename[s](), name the new helper initial_cleanup_rename(), and leave the big comment in the code about why we can't do all the cleanup at once.
