fix: preserve nulls in array_has_any/all empty-needle path

[yashrb24]

Which issue does this PR close?

• Closes array_has_any/array_has_all results depend on other rows when needles are NULL #24985.

Rationale for this change

When every needle array in a batch is NULL or empty, array_has_any and
array_has_all use an empty-needle fast path.

That path currently drops the input null masks, so a row can return a different
result depending on the contents of another row in the batch.

What changes are included in this PR?

Preserves the combined null mask from the haystack and needle when constructing
the fast-path result.

Non-NULL empty needles will keep the existing behavior:

• array_has_any(array, []) returns false
• array_has_all(array, []) returns true

What is the testing strategy for this PR?

Added a SQLLogicTest covering this edge case

Are there any user-facing changes?

Yes. NULL input rows now return NULL consistently in the empty-needle path.
There is no API change.
