Pull Request resolved: #16724 Introduce CUDAGuard and CUDAStreamGuard from cuda/runtime/ to aoti/slim/cuda/ to support slimtensor requirement while get rid of potential circular dependency: - cuda_backend/main_functionalities -> aoti/slimtensor -> cuda_backend/cuda_guard This change: - copy guard.h, guard.cpp and test files from backend/cuda_backend to backend/aoti/slim/cuda/ - original guard.h, guard.cpp will be deleted on the final integration step. ghstack-source-id: 336190672 @exported-using-ghexport Differential Revision: [D91056808](https://our.internmc.facebook.com/intern/diff/D91056808/)
Pull Request resolved: #16446 Add SlimTensor-based implementations of AOTI shim functions for tensor creation: 1. `aoti_torch_create_tensor_from_blob_v2()` - Creates a non-owning SlimTensor that wraps existing memory using the `from_blob()` factory Both functions support CPU and CUDA devices and handle all 7 SlimTensor dtypes. Also add `memory_slim.h` and `memory_slim.cpp` with SlimTensor-based shim implementations for working on new API while not impact the current pipeline. Will use memory_slim.{h/cpp} to replace current memory.{h/cpp} when everything has been set up. ghstack-source-id: 336190664 @exported-using-ghexport Differential Revision: [D90126247](https://our.internmc.facebook.com/intern/diff/D90126247/)
