4b977a5d72 Fixed #35444 -- Added generic support for Aggregate.order_by. 
This moves the behaviors of `order_by` used in Postgres aggregates into
the `Aggregate` class. This allows for creating aggregate functions that
support this behavior across all database engines. This is shown by
moving the `StringAgg` class into the shared `aggregates` module and
adding support for all databases. The Postgres `StringAgg` class is now
a thin wrapper on the new shared `StringAgg` class.

Thank you Simon Charette for the review.

65ad4ade74 Refs #28900 -- Made SELECT respect the order specified by values(*selected). 
Previously the order was always extra_fields + model_fields + annotations with
respective local ordering inferred from the insertion order of *selected.

This commits introduces a new `Query.selected` propery that keeps tracks of the
global select order as specified by on values assignment. This is crucial
feature to allow the combination of queries mixing annotations and table
references.

It also allows the removal of the re-ordering shenanigans perform by
ValuesListIterable in order to re-map the tuples returned from the database
backend to the order specified by values_list() as they'll be in the right
order at query compilation time.

Refs #28553 as the initially reported issue that was only partially fixed
for annotations by d6b6e5d0fd.

Thanks Mariusz Felisiak and Sarah Boyce for review.

Added a note about the potential race condition in prefetch_related()
that could produce an inconsistent result, one that does not correspond
to any point in the database history.

88b5b7b8e5 Corrected QuerySet.prefetch_related() note about GenericRelation(). 
GenericRelation is a reverse generic relationship so it's always
homogeneous. Mentioning this as a restriction is confusing.

one operand evaluates to true.
