The rough draft idea is: if the computing engine(trino) can obtain the sorting information of the shard, the statistical information of the file is recorded in iceberg’s meta, and sort_order_id != 0 indicates that the file has been sorted. Then the steps of PartialSort or PartialTopN can be omitted, and in when reading data, the sorting operation in the shard can be avoided. I've got an initial plan and implemented some basic code.

The specific work can be decomposed into the following two tasks
