LibDebug: Store optional parent_offset in Dwarf::DIE objects
In the current implementation, only DIE objects that are created via DIE::for_each_child() will have parent offsets. DIE objects that are created with CompilationUnit::get_die_at_offset() do not currently store a parent offset. We may improve this in the future, but this is enough for what we currently need.
