URL: https://github.com/apache/doris/pull/66824
Nullable predicate columns always carry their null maps through predicate
evaluation and selector copying, even when a scanned batch is known to contain
no NULL values. This adds unnecessary work to a common scan path. This change
tracks each predicate column's batch null state, evaluates proven no-NULL
batches through the nested column, and rebuilds an all-zero null map only when
producing nullable output. Unknown or NULL-containing batches continue to use
the existing nullable path.
