Generalize existing SQL UDF functions to all types

[sviscaino]

Following #18581, this extends the following SQL invoked functions to accept any type as input, not just varchar and double:
array_frequency, array_duplicates, array_has_duplicates, array_intersect

Test plan -
mvn test -Dtest=TestArrayIntersectFunction,TestArraySqlFunctions test

== RELEASE NOTES ==

General Changes
* Extend :func:`array_frequency`, :func:`array_duplicates`, :func:`array_has_duplicates`, :func:`array_intersect(array(array(E))` to accept any type as input instead of only varchar/double

A trick with find_first was needed here because we can't do cast(NULL as T) in the function body

This is great! Can you add a couple of test to show a) any new types that would work now and b) any that would not (like rows with nulls or something that can't be compared) for all the functions that you fixed? I see for some but also add the error cases say something like: ARRAY[ROW(1, null), ROW(null, 2)] etc.

Added some more unit tests
