delta_store: support iteration with is_deleted virtual column

This patch adds support to delta stores (i.e. DMS and delta files) for
iterating with an IS_DELETED virtual column. A diff scan will include
IS_DELETED in the projection so that clients can tell if a row was deleted
in the requested time range.
