pack-bitmap: implement `bitmap_writer_has_bitmapped_object_id()`

Prepare to implement pseudo-merge bitmap selection by implementing a necessary new function, `bitmap_writer_has_bitmapped_object_id()`. This function returns whether or not the bitmap_writer selected the given object ID for bitmapping. This will allow the pseudo-merge machinery to reject candidates for pseudo-merges if they have already been selected as an ordinary bitmap tip.
