[SPARK-41778][SQL] Add an alias "reduce" to ArrayAggregate

[ueshin]

What changes were proposed in this pull request?

Adds an alias "reduce" to ArrayAggregate.

Also modified the higher-order functions to also copy tags when binding to propagate them properly.

Why are the changes needed?

Presto provides the function: https://prestodb.io/docs/current/functions/array.html#reduce.

Does this PR introduce any user-facing change?

Yes, a new alias for ArrayAggregate.

For example:

SELECT reduce(array(1, 2, 3), 0, (acc, x) -> acc + x);
SELECT reduce(array(1, 2, 3), 0, (acc, x) -> acc + x, acc -> acc * 10);

as the same as "aggregate":

SELECT aggregate(array(1, 2, 3), 0, (acc, x) -> acc + x);
SELECT aggregate(array(1, 2, 3), 0, (acc, x) -> acc + x, acc -> acc * 10);

How was this patch tested?

Added/modified tests.
