Add Iceberg dereference pushdown on the physical input size level

[findinpath]

As showcased on https://github.com/trinodb/trino/pull/17145 , dereference pushdown does not work yet on the physical level for Iceberg. Even though the connector filters out nested data information which is not needed, this data is still read from ORC/Parquet (haven't checked yet AVRO) files.

• [ ] Apply the dereference pushdown at the physical level on ORC in Iceberg (https://github.com/trinodb/trino/issues/17201)
• [x] https://github.com/trinodb/trino/pull/17387

Add the necessary logic to strip the schema being read from the columnar data files so that only the relevant nested information is read from the source file.

It seems the same issue is with avro format as well.

Avro isn't columnar so we may not be able to improve Avro reads, but that's a non-goal for this issue. Let's have this issue focused on ORC and Parquet.
