* [Refactor] Remove cache existence check in kernel saving logic

- Eliminated redundant checks for existing cache paths in `AutotuneResult` and `AutoTunerCache` classes, simplifying the kernel saving process.
- Ensured that the cache directory is always created before saving kernel source code, improving reliability in kernel storage.

* [Enhancement] Improve input tensor compatibility checks in AutoTuner

- Enhanced the input tensor caching logic in the AutoTuner class to ensure compatibility between cached tensors and newly generated tensors during configuration trials.
- Added detailed logging to warn users about potential mismatches in tensor properties, including shape and dtype, when caching is enabled.
- Implemented a mechanism to regenerate input tensors if compatibility issues are detected, improving the robustness of the autotuning process.

* [Refactor] Update L2 persistent map initialization in CUDA wrapper

- Adjusted the L2 persistent map initialization function to use a consistent size parameter for cache limits and byte counts, improving clarity and reducing potential errors in memory management.
- Simplified the formatting of the initialization function to enhance readability and maintainability of the code.

* Update tilelang/autotuner/__init__.py
