Co-authored-by: LeiWang1999 <leiwang1999@outlook.com>

**Summarize part of the rebase pr:**

1. **Support T.thread_return() → CUDA return syntax**  
   Added support for translating `T.thread_return()` to CUDA's native `return` statement.

2. **Dynamic type support for function inputs**  
   Functions now accept dynamically typed parameters using `typing`:
   ```python
   dyn_type = T.int32 or T.float
   @T.prim_func
   def main(
       a: dyn_type,
   )
   ```

3. **Device Function Codegen**  
   Added support for generating `__device__` functions in CUDA:
   ```python
   @I.ir_module
   class Module:
       @T.prim_func(private=True)
       def add(a: T.int32, b: T.int32) -> T.int32:
           return a + b

       @T.prim_func
       def main(
           A: T.Buffer((128, 128), "int32"),
           B: T.Buffer((128, 128), "int32"),
           C: T.Buffer((128, 128), "int32"),
       ):
           T.func_attr({"global_symbol": "main"})
           length: T.int32 = Module.add(64, 64)  # Host call
           for bx in T.thread_binding(length, "blockIdx.x"):
               for tx in T.thread_binding(length, "threadIdx.x"):
                   C[bx, tx] = Module.add(A[bx, tx], B[bx, tx])  # Device call
   ```
   After compilation, `add` becomes a CUDA `__device__` function.

4. **Cython-based Python/C++ interop**  
   Replaced ctypes with Cython for all Python/C++ interactions:
   - Python → C++ calls
   - C++ → Cython calls  
   This improves performance by around 100x and reduces CPU overhead during compile/runtime.

5. **FP8 data type standardization**  
   Migrated `e5m2_float8` and similar types to Torch-standardized variants`float8_e5m2` and etc.

* Enhance test coverage by adding LLVM requirement decorator to multiple function call tests. This ensures that tests for argument count, type code, null data pointer, and dimensionality checks are only executed when LLVM is available, improving test reliability and clarity.

* lint fix

* Fix software pipeline stage annotation and update optional config handling in StmtSimplifier

* Add Python executable detection in CMake configuration and update TVM submodule reference. Remove unused vectorization tests for improved clarity.

* Update TVM submodule reference and refactor FFI registration to use static initialization blocks for improved organization and clarity.

* Refactor attribute handling in layout and IR nodes to use reflection registration. This change replaces the VisitAttrs method with a RegisterReflection method for improved clarity and organization across multiple classes, including KernelLaunchFrameNode, WarpSpecializeFrameNode, LayoutNode, FragmentNode, and SwizzledLayoutNode.

* finish rebase

* tvm update

* Refactor FFI registration across tilelang modules to use the updated `tvm.ffi` namespace. This includes changes in various files to replace `tvm._ffi` with `tvm.ffi`, enhancing consistency and clarity in the codebase.

* lint fix

* Update TVM submodule reference and modify CUDA runtime argument handling to use the new runtime constants for improved clarity and consistency.

* lint fix

* Refactor tensor data type references from "e4m3_float8" and "e5m2_float8" to "float8_e4m3" and "float8_e5m2" across multiple files for consistency and clarity.
