AggregatingStep ignores it anyway, and it leads to the following error
in getSortDescriptionFromGroupBy(), like in [1]:

v2: revert change to getSortDescriptionFromGroupBy() after
GroupingSetsRewriterVisitor had been introduced

With projections, GROUP BY/ORDER BY in query, optimize_aggregation_in_order,
GROUP BY's InputOrderInfo was used incorrectly for ORDER BY.

* Fix GROUP BY AggregateFunction
finalizeChunk() was unconditionally converting AggregateFunction to the
underlying type, however this should be done only if the aggregate was
applied.
So pass names of aggregates as an argument to the finalizeChunk()
Fuzzer report [1]:
Logical error: 'Bad cast from type DB::ColumnArray to DB::ColumnAggregateFunction'. Received signal 6 Received signal Aborted (6)
For the following query:
SELECT
arraySort(groupArrayArray(grp_simple)),
grp_aggreg,
arraySort(groupArrayArray(grp_simple)),
b,
arraySort(groupArrayArray(grp_simple)) AS grs
FROM data_02294
GROUP BY
a,
grp_aggreg,
b
SETTINGS optimize_aggregation_in_order = 1

v2: fix conflicts in src/Interpreters/InterpreterSelectQuery.cpp
v3: Fix header for GROUP BY AggregateFunction WITH TOTALS
v4: Add sanity check into finalizeBlock()
v5: Use typeid_cast<&> to get more sensible error in case of bad cast (as suggested by @nickitat)
v6: Fix positions passed to finalizeChunk()
