IMPALA-14923: Run Iceberg tests with no block locations
When block locations are not available Impala works quite differently.
E.g. it doesn't create TScanRanges in the Frontend, but generates them
in the backend from TFileSplitGeneratorSpec objects.
We already have test_disabled_block_locations.py that disables block
location loading but it didn't test Iceberg V3 tables.
This patch executes a few Iceberg tests without block locations to
somewhat simulate the behavior on object stores. This way we can
catch bugs in pre-commit that would otherwise only be found later.

> It is possible to disable block location information via core-site.xml:
> {noformat}
> <property>
> <name>impala.preload-block-locations-for-scheduling</name>
> <value>false</value>
> </property>
> {noformat}
>
> Executing a set of tests with disabled block locations could catch a few
> errors in time.
