IMPALA-13074: Add sink node to Web UI's graphical plan for DDL/DML queries

>From now on if a plan fragment's root data sink is a table sink, a
multi data sink or a merge sink, it will be included in the json
response and shown on the Web UI as parent of the plan fragment.

Testing
 * adopted and refined impala-http-handler-test
 * added new tests for related sink types
 * tested manually on WebUI with
   - CTAS statements
   - UPDATE statements on Iceberg tables
   - DELETE statements on Iceberg tables
   - MERGE statements on Iceberg tables

> The query plan shows the nodes that take part in the execution, forming a 
> tree structure.
> It can be displayed in the CLI by issuing the EXPLAIN <query> command. When 
> the actual query is executed, the plan tree can also be viewed in the Impala 
> Web UI in a graphic form.
> However, the explain string and the graphic plan tree does not match: the top 
> node is missing from the Web UI.
> This is especially confusing in case of DDL and DML statements, where the 
> Data Sink is not displayed. This makes a SELECT * FROM table 
> indistinguishable from a CREATE TABLE AS SELECT, since both only displays the 
> SCAN node and omit the WRITE_TO_HDFS and SELECT node.
> It would make sense to include the WRITE_TO_HDFS node in DML/DDL plans.
