* Update legalize_safe_memory_access.cc
* Add cache path handling and file locking in Cython adapter
- Introduced a new cache path based on the code hash for the Cython JIT adapter, enhancing cache management.
- Added a lock file mechanism to ensure safe access during cache operations, improving concurrency handling.
- These changes aim to optimize the compilation process and prevent race conditions during library loading.
* lint fix
* refactor

* Add GlobalCopyPatternDetector to identify global memory copy patterns
- Introduced a new class, GlobalCopyPatternDetector, to detect specific memory copy patterns in statements.
- Enhanced the PipelinePlanner to utilize this detector for determining copy stages based on global and local memory scopes.
- Improved code clarity and maintainability by encapsulating detection logic within the new class.
* Refactor copy stage detection logic in pipeline planning
- Simplified the determination of copy stages by directly assigning the result of GlobalCopyPatternDetector to pinfo.copy_stage.
- Removed redundant checks for read and write scopes, enhancing code clarity and maintainability.
* lint fix
