fix: Implement NeededFields feature in RecordReader (#43523)
Related to #43522

Currently, passing partial schema to storage v2 packed reader may
trigger SEGV during clustering compaction unit test.

This patch implement `NeededFields` differently in each `RecordReader`
imlementation. For now, v2 will implemented as no-op. This will be
supported after packed reader support this API.
