* [Enhancement] Update AllReduce operation to include thread offset in kernel generation

- Modified the `ReduceOp::Lower` method to incorporate the thread offset in the AllReduce kernel generation for the sm_90 architecture.
- This change improves the accuracy of thread management during reduction operations, enhancing performance on specific GPU architectures.

* [Enhancement] Refactor thread offset handling in AllReduce kernel generation

- Updated the `ReduceOp::Lower` method to streamline the handling of thread offset for AllReduce operations, ensuring consistent usage across different architectures.
- This change enhances code clarity and maintains performance improvements for the sm_90 architecture by reducing redundancy in thread offset calculations.
