test: Enable native e2e test for array_split_into_chunks null literal

[allenshen13]

Summary

Match Velox's behavior for array_split_into_chunks(array[], n) so the inherited
native e2e test (TestSqlInvokedFunctions#testArraySplitIntoChunks) can run
unmodified:

• Add an explicit empty-array check to the SQL definition that throws
  "Cannot split an empty array." — byte-identical to Velox's
  VELOX_USER_CHECK_GT(inputSize, 0, "Cannot split an empty array.") in
  velox/functions/prestosql/ArrayFunctions.h.
• Remove the // TODO override in presto-native-tests/.../TestSqlInvokedFunctions.java
  that was suppressing the entire native run of testArraySplitIntoChunks.
• Extend AbstractTestSqlInvokedFunctions.testArraySplitIntoChunks with empty-array,
  exact-fit, and boolean-element cases. These run against H2 (Java) directly and
  against the native engine via the inherited TestSqlInvokedFunctions.
• Add TestArraySqlFunctions.testArraySplitIntoChunksEmptyArray covering empty
  arrays of bigint / varchar / integer / double.

Tracks #27429.

Behavior change

array_split_into_chunks(array[], n) with n > 0 failed with
the sequence builtin's error: "sequence stop value should be greater than or equal to start value if step is greater than zero...". After this PR it
throws "Cannot split an empty array.", identical to what Velox throws,
so the same call fails the same way on both engines and the inherited native
e2e test can assert one regex against both. The original sequence failure throw is
ambiguous and should be changed.

Test plan

• TestArraySqlFunctions#testArraySplitIntoChunksEmptyArray passes
• AbstractTestSqlInvokedFunctions#testArraySplitIntoChunks passes (Java/H2)
• TestSqlInvokedFunctions#testArraySplitIntoChunks passes against the native engine

Merge order

This PR must wait for facebookincubator/velox#16923 to land and for the
Velox SHA pinned by Presto to advance past it. That PR fixes the null-literal
overload-resolution half of #27429; until it's in, the inherited test's
array_split_into_chunks(null, 2) assertion will still fail on native.

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Adjusts the SQL-implemented array_split_into_chunks function to return an empty array of arrays when given an empty input array, and adds corresponding unit and e2e tests while re-enabling the native engine test override.

File-Level Changes

Change	Details	Files
Handle empty input arrays in array_split_into_chunks SQL implementation instead of throwing on invalid sequence() bounds.	Wrap existing logic in an IF that checks cardinality(input) = 0 and directly returns an empty array when true Keep existing validation that sz > 0 and the limit on the maximum number of chunks before calling sequence() and slice()	presto-sql-helpers/presto-sql-invoked-functions-plugin/src/main/java/com/facebook/presto/scalar/sql/ArraySqlFunctions.java
Add unit tests covering empty array inputs for array_split_into_chunks in scalar array SQL function tests.	Introduce testArraySplitIntoChunksEmptyArray with multiple element types (bigint, varchar, integer, double) Assert that array_split_into_chunks returns an empty list of arrays for empty input arrays regardless of chunk size	presto-main-base/src/test/java/com/facebook/presto/operator/scalar/sql/TestArraySqlFunctions.java
Extend SQL-invoked function e2e tests to assert behavior for empty arrays and re-enable native test override.	Add an assertion in AbstractTestSqlInvokedFunctions.testArraySplitIntoChunks that an empty bigint array input returns an empty array-of-arrays Remove the testArraySplitIntoChunks override in TestSqlInvokedFunctions so that it inherits and runs the base test against the native engine	presto-tests/src/main/java/com/facebook/presto/tests/AbstractTestSqlInvokedFunctions.java presto-native-tests/src/test/java/com/facebook/presto/nativetests/TestSqlInvokedFunctions.java

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#27429	Ensure array_split_into_chunks correctly handles a NULL literal array argument (e.g., select array_split_into_chunks(null, 2)) by resolving to array(unknown) and not failing operator resolution.	❌	The PR only changes the SQL function implementation to special-case empty input arrays and adds corresponding tests. It does not modify type resolution or null-literal handling, and no new tests cover array_split_into_chunks(null, 2), so the original NULL literal failure is not addressed.
#27429	On the Velox side, simplify and correct array_split_into_chunks registration (use a generic registration instead of many concrete types, remove unsupported int128_t, and add a decimal unit test).	❌	This PR is in the Presto repository and only changes Presto SQL function code and tests. It does not touch Velox registrations or Velox tests; those are deferred to a separate Velox PR referenced in the description.
