    [cherry-pick](branch-3.0) Don't prematurely erase DeleteRows in reading 
iceberg table with position delete (#47977) (#48309)
    
    
    Issue Number: close #41460
    
    Problem Summary:
    When reading the Iceberg table, previously read `DeleteRows` should not
    be released immediately, as the Iceberg data file is split into multiple
    `IcebergSplit`s for execution. These `IcebergSplit`s belong to the same
    data file, meaning they share the same `DeleteRows`. Therefore,
    `DeleteRows` in the `DeleteFile` should not be released prematurely.
    Instead, they should be released when the shared_kv is reset, at which
    point all `DeleteRows` will be freed along with the cached `DeleteFile`.
