Which issue does this PR close?
Note: This is a WIP PR, I'm still working on testing the support and also only allowing reads from COW tables.
Closes #1676
Rationale for this change
Auron currently does not support native execution for Iceberg DSv2 reads backed by BatchScanExec, so all Iceberg scans fall back to Spark execution. This change enables native execution for Iceberg COW table scans to unlock native file scan performance for Parquet/ORC Iceberg workloads.
What changes are included in this PR?
Are there any user-facing changes?
Yes. When enabled via configuration, Iceberg COW table scans can now run through native execution. No behavior change when the feature flag is disabled.
How was this patch tested?
