This change collects the "struct pack_midx_entry *entries" list and its count into the context. Update write_midx_oid_fanout() and write_midx_oid_lookup() to take the context directly, as these are easy conversions with this new data. Only the callers of write_midx_object_offsets() and write_midx_large_offsets() are updated here, since additional data in the context before those methods can match chunk_write_fn.
