Review Comment:
Hm, the `plan` inside the LogicalPlanBuilder? You could just skip the
builder completely:
```
let input = consumer.consume_rel(input).await?;
...
let group_exprs = normalize_cols(group_exprs, &input)?;
let aggr_exprs = normalize_cols(aggr_exprs, &input)?;
Ok(LogicalPlan::Aggregate(Aggregate::try_new(
Arc::new(input),
group_exprs,
aggr_exprs,
)?))
```
But either is fine by me. @alamb do you have preferences, or thoughts on
this overall (I feel it's weird the LogicalPlanBuilder::aggregate does this
magic, but changing that is break, but also adding the
`aggregate_without_implicit_group_by_exprs` feels a bit sad API...
