1. [#2543] feat(spark-connector): support row-level operations to iceber… …

   …g Table (#3243)
   
   ### What changes were proposed in this pull request?
   
   - refactor table implementation, make `SparkIcebergTable` extend Iceberg
   `SparkTable`, and `SparkHiveTable` extend Kyuubi `HiveTable`.
   
   - support row-level operations to iceberg Table
   
   ```
   1. update tableName set c1=v1, c2=v2, ...
   
   2. merge into targetTable t
      using sourceTable s
      on s.key=t.key
      when matched then ...
      when not matched then ...
   
   3. delete from table where xxx
   ```
   
   ### Why are the changes needed?
   
   1. For spark-connector in Iceberg, it explicitly uses `SparkTable` to
   identify whether it is an Iceberg table, so the `SparkIcebergTable` must
   extend `SparkTable`.
   
   2. support row-level operations to iceberg Table.
   
   Fix: #2543
   
   ### Does this PR introduce any user-facing change?
   Yes, support update ... , merge into ..., delete from ...
   
   ### How was this patch tested?
   New ITs.
