#31442

[Feature] (iceberg-writer) Implements iceberg sink basic functionality for inserting into table.

Currently only insert into and CTAS are supported. Among them, insert into supports unpartitioned tables and partitioned tables, but partitioned tables only support identity transform partitioned tables.

Future work:

• Complete partitioned table transform functionality.
• Sorting function.
• Insert overwrite function.
• More features like update, delete and merge.
