Lei Wang 47caf21901 [Bugfix] Support T.clear for let binding (#268)
* Fix indentation in JIT adapter wrapper to ensure consistent formatting of return statement in generated C code.

* Enhance Fill Operation in TileLang

- Updated the Fill constructor to support BufferLoad instances, adding checks for ramp indices and ensuring only stride 1 ramps are processed.
- Introduced a region array to manage the bounds of the fill operation, improving error checking for static regions.
- Modified the MakeSIMTLoop method to utilize the new region array for loop variable bounds, enhancing flexibility in kernel generation.
- Updated the fill and clear functions in fill.py to accept both tir.Buffer and tir.BufferRegion types, improving usability and type handling.

* Refactor Fill Operation and Improve Readability

- Simplified the Fill constructor by enhancing the handling of BufferLoad instances and ensuring proper checks for ramp indices.
- Improved error messages for region size checks to enhance clarity.
- Cleaned up formatting in the Fill method for better readability.
- Added a blank line in the matmul function test to improve code organization.
- Introduced a blank line in the fill function to enhance readability in fill.py.

* Add matrix multiplication functionality and test in TileLang

- Introduced a new test file `test_tilelang_language_clear.py` that implements a matrix multiplication function using TileLang's primitives.
- The `matmul` function defines a kernel for performing tile-level GEMM operations with customizable block sizes and data types.
- Added a `run_matmul` function to compile and execute the kernel, along with a test function to validate the implementation.
- Updated the `__init__.py` in the utils module to include `map_torch_type`, enhancing type handling for tensor operations.

* lint fix
