[24/32] builtin/pack-objects: Communicate the compatibility hash through struct pack_idx_entry

Commit Message

When pack-objects is run all objects in the repository should already
have a compatibilty hash computed so it is just necessary to read
the existing mappings and store the value in struct pack_idx_entry.
