Description
### Description
- GlutenCheckExpression currently falls back to internal row for certain complex/unsupported types.
- In some cases like LONG_MAX glutenCheckExpression calls collect which can lead to failures.
- Refactor the code to allow tests to call fallback evaluation directly
Contributor guide
Research direction
Start at GlutenCheckExpression and inspect the fallback path where collect is called for complex or unsupported types, including the LONG_MAX case. Refactor the entry point so the specific tests can invoke fallback evaluation directly, then verify those tests no longer depend on collect and still pass.
