(experimental) Iceberg transform values for partition and sort fields.

Example: 

 // Build a table with partition spec (minimal configuration)
 Table partitionedTable = Table.Builder.create(scope, "PartitionedTable")
         .tableName("partitioned_table")
         .namespace(namespace)
         .openTableFormat(OpenTableFormat.ICEBERG)
         .icebergMetadata(IcebergMetadataProperty.builder()
                 .icebergSchema(IcebergSchemaProperty.builder()
                         .schemaFieldList(List.of(SchemaFieldProperty.builder().name("event_date").type("date").required(true).build(), SchemaFieldProperty.builder().name("event_name").type("string").build()))
                         .build())
                 .icebergPartitionSpec(IcebergPartitionSpec.builder()
                         .fields(List.of(IcebergPartitionField.builder()
                                 .sourceId(1)
                                 .transform(IcebergTransform.IDENTITY)
                                 .name("date_partition")
                                 .build()))
                         .build())
                 .build())
