* lint fix

* lint fix

* test fix

* test fix

* rebase

* Update builtin.cc

**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.
