* [Enhancement] Add argument simplification option to StmtSimplifier

- Introduced a new `simplify_arguments` flag in the `StmtSimplifier::Apply` method to control argument simplification behavior.
- Updated the `Simplify` function to accept the new flag, allowing for enhanced flexibility in the simplification process.
- Adjusted the `LowerAndLegalize` and `_Simplify` functions to utilize the new argument, ensuring consistent behavior across the codebase.
- Added comments to clarify the purpose of the new flag and its impact on simplification logic.

* lint fix

* [Enhancement] Improve layout inference and reduce operation handling

- Updated `ParallelOp::InferLayout` to check for pure buffer stores, enhancing layout inference logic.
- Modified `ReduceOp::Lower` to include all threads in the AllReduce operation, improving performance on specific architectures.
- Added a TODO comment in `AllReduce` to consider merging synchronization barriers for optimization.

* [Enhancement] Add input validation for GEMM parameters

- Introduced checks to ensure that the dimensions M and N are divisible by their respective warp sizes (kMPerWarp and kNPerWarp) in the Gemm::ComputeWarpPartition method.
- Added informative error messages to assist in debugging when the input parameters do not meet the required conditions.
