Original cherry-pick message follows:

Merge pull request #2129 from Altinity/feature/antalya-26.6/pr-1761

Antalya 26.6: Support for 'time' type in Iceberg
# Conflicts:
#	src/Storages/ObjectStorage/DataLakes/Iceberg/IcebergWrites.cpp
#	src/Storages/ObjectStorage/DataLakes/Iceberg/Utils.cpp
#	src/Storages/ObjectStorage/DataLakes/Iceberg/Utils.h
#	tests/integration/test_database_iceberg/test.py
Kept both sides in the additive conflicts (decimal partition-value
support on antalya-26.8 plus the new Time/Time64 helpers from #2129).

Adapted: getAvroType() gained an `Int32 field_id` parameter on antalya-26.8
(unique Avro `fixed` names for decimal partition fields), so the new
make_annotated_type() lambda from #2129 takes and forwards the field id.
