SparseFillEmptyRows의 그라데이션입니다.
`[N]` 형태의 reverse_index_map 벡터와 `[N_full]` 형태의 grad_values(여기서 `N_full >= N`)를 취하고 데이터를 `d_values` 또는 `d_default_value`에 복사합니다. 여기서 `d_values`는 `[N]` 모양이고 `d_default_value`는 스칼라입니다.
d_values[j] = grad_values[reverse_index_map[j]] d_default_value = sum_{k : 0 .. N_full - 1} ( grad_values[k] * 1{k는 reverse_index_map에 없음})
