[opt](iceberg)Optimize count* in batch mode

[wuwenchi]

What problem does this PR solve?

Problem Summary:

When using batch mode, if count* optimization is available, the traditional mode will be used.
Otherwise, it is impossible to calculate how many counts should be assigned to each split because we do not know how many splits there are.
