which there's a lot

**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

* [Enhancement] passing verbose to LibraryGenerator

This PR enables passing a verbose parameter to LibraryGenerator
via CtypesKernelAdapter and CythonKernelAdapter.
When verbose is set to True,  we will print out the NVCC
compilation command.

This slightly improves debuggability.

cmake doesn't take the nvcc specified by CUDA_HOME by default.
Consequently, the follow command failed for me because cmake still
used the nvcc from the default location (e.g. in my case
/usr/local/cuda/bin/nvcc):

```
$ PATH=/home/yangche/cuda-12.8/bin:$PATH CUDA_HOME=/home/yangche/cuda-12.8 pip install -e . -v
```

This minor fix enforces cmake to use the nvcc specified by the CUDA_HOME env.

This reverts commit e8cc372f.
