tree: convert parse_tree_indirect to struct object_id

Convert parse_tree_indirect to take a pointer to struct object_id.
Update all the callers.  This transformation was achieved using the
following semantic patch and manual updates to the declaration and
definition.  Update builtin/checkout.c manually as well, since it uses a
ternary expression not handled by the semantic patch.
