RETURNING support for Delete Operation

RETURNING support for Delete Operation

使用 gorm.DB 删除， result的长度是1

	var result []*model.Record
	err = db.WithContext(ctx).Clauses(clause.Returning{}).
		Where(query.Record.ID.Eq(record.ID).RawExpr()).
		Delete(&result).Error
	if err != nil {
		t.Fatal(err)
	}
	if len(result) != 1 {
		t.Fatal("delete record failed")
	}

使用gen删除，长度是0，returning 不生效

	var result []*model.Record
	_, err = query.Record.WithContext(ctx).
		Where(query.Record.ID.Eq(record.ID)).
		Returning(&result).Delete()
	if err != nil {
		t.Fatal(err)
	}
	if len(result) != 1 {
		t.Fatal("delete record failed")
	}

我最开始以为是gorm.DB的问题，后面发现是gen不支持
go-gorm/gorm#7515

试下直接.Delete(&result)
