IMPALA-14833: Add Iceberg V3 write-default support to MERGE INSERT
Earlier, MERGE INSERT with a column permutation that omitted
columns with write-defaults would fill them with NULL. Now, for
Iceberg tables, unmentioned columns use the write-default value
defined in the Iceberg schema metadata (falling back to NULL when
no write-default is set).
Testing:
- Added e2e tests covering:
- MERGE INSERT with column permutation omitting a column that
has a write-default (verifies default is applied)
- MERGE INSERT with all columns explicit (default not used)
- MERGE INSERT with explicit NULL (overrides write-default)
- MERGE INSERT with all data types that support write-defaults
(INT, BIGINT, FLOAT, DOUBLE, STRING, DATE, BOOLEAN, DECIMAL)
