Fix allow_experimental_projection_optimization with enable_global_with_statement
...
allow_experimental_projection_optimization requires one more
InterpreterSelectQuery, which with enable_global_with_statement will
apply ApplyWithAliasVisitor if the query is not subquery.
But this should not be done for queries from
MergeTreeData::getQueryProcessingStage()/getQueryProcessingStageWithAggregateProjections()
since this will duplicate WITH statements over and over.
This will also fix scalar.xml perf tests, that leads to the following
error now:
scalar.query0.prewarm0: DB::Exception: Stack size too large.
And since it has very long query in the log, this leads to the following
perf test error:
_csv.Error: field larger than field limit (131072)
