What did this pull request do?

实现mysql中的 field() 函数，方便自定义 排序的实现

User Case Description

# gen
***.Select(t1.ALL,  t1.BindStatus.Filed(5, 2, 4, 3, 1).As("status")).Order(field.NewField(t1.TableName(), "status"))
# sql
SELECT `t1`.*,FIELD(`t1`.`bind_status`, 5,2,4,3,1) AS `status` FROM `t1` ORDER BY `status`

通过filed字段实现自定义排序,同理其他需要field函数的也可以使用这个方法
所以不单独实现 ORDER BY FIELD(`t1`.`bind_status`, 5,2,4,3,1)
