f387d024fc Refs #28333 -- Added partial support for filtering against window functions.
Adds support for joint predicates against window annotations through
subquery wrapping while maintaining errors for disjointed filter
attempts.

The "qualify" wording was used to refer to predicates against window
annotations as it's the name of a specialized Snowflake extension to
SQL that is to window functions what HAVING is to aggregates.

While not complete the implementation should cover most of the common
use cases for filtering against window functions without requiring
the complex subquery pushdown and predicate re-aliasing machinery to
deal with disjointed predicates against columns, aggregates, and window
functions.

A complete disjointed filtering implementation should likely be
deferred until proper QUALIFY support lands or the ORM gains a proper
subquery pushdown interface.

c53af56613 Fixed #29847 -- Ensured proper ordering in queries.
Even though good databases tend to keep the result sorted by the/one
window expression and the planners are smart enough to not resort if not
required, it is not valid to rely on this.

MariaDB specifically did return whatever order it wanted, which is
completely okay. Now we sort towards the expected data for all databases.
