pack-objects: move tree_depth into 'struct packing_data'
This reduces the size of 'struct object_entry' and therefore
makes packing objects more efficient.
This also renames cmp_tree_depth() into tree_depth_compare(),
as it is more modern to have the name of the compare functions
end with "compare".
