* [Refactor] Update Vectorization Functions to Accept Analyzer Parameter

- Modified `VectorizeLoop` and related functions to accept an `arith::Analyzer` parameter, enhancing their capability to perform analysis during vectorization.
- Updated multiple instances in `copy.cc`, `fill.cc`, `parallel.cc`, and layout inference files to utilize the new analyzer parameter for improved performance and correctness.
- Ensured consistency across vectorization logic by integrating the analyzer into existing workflows, facilitating better optimization opportunities.

* [Fix] Corrected PostOrderVisit call in loop_vectorize.cc

- Updated the PostOrderVisit function to analyze the body of the loop node instead of the node itself, ensuring proper handling of nested loops during vectorization analysis.
