Fixed #31679 -- Delayed annotating aggregations.

Browse Source 
By avoiding to annotate aggregations meant to be possibly pushed to an
outer query until their references are resolved it is possible to
aggregate over a query with the same alias.

Even if #34176 is a convoluted case to support, this refactor seems
worth it given the reduction in complexity it brings with regards to
annotation removal when performing a subquery pushdown.
