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.

Aligns the argument with SQL standards already used in Window.order_by and sets up for adding support to Aggregate.

Fixed #35339 -- Fixed PostgreSQL aggregate's filter and order_by params order.

2024-04-25T20:40:03Z

Updated OrderableAggMixin.as_sql() to separate the order_by parameters from the filter parameters. Previously, the parameters and SQL were calculated by the Aggregate parent class, resulting in a mixture of order_by and filter parameters. Thanks Simon Charette for the review.
