Pull Request resolved: #15857 # aoti_torch_new_tensor_handle Shim for Cuda Backend ## summary This diff introduces the `aoti_torch_new_tensor_handle` shim for the CUDA backend. The shim is a wrapper around the `aoti_torch_new_tensor_handle` function, which creates a new tensor handle from an existing tensor, to unblock the custom triton kernel usage The diff affects the following files: * `fbcode/executorch/backends/aoti/common_shims.h`: The function prototype is declared. * `fbcode/executorch/backends/apple/metal/runtime/shims/memory.cpp`: A fallback implementation is provided for the Apple Metal backend to keep its behavior. * `fbcode/executorch/backends/cuda/runtime/shims/tests/test_aoti_torch_new_tensor_handle.cpp`: A test file is added for the CUDA backend. ghstack-source-id: 323864197 @exported-using-ghexport Differential Revision: [D87254968](https://our.internmc.facebook.com/intern/diff/D87254968/)
