Add `aoti_torch_new_tensor_handle()` - Creates a new tensor handle that shares storage with the original tensor. Uses SlimTensor's copy constructor which shares the SharedPtr<Storage>, so both tensors reference the same memory.

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. Differential Revision: [D90126247](https://our.internmc.facebook.com/intern/diff/D90126247/)

SlimTensor uses SharedPtr-based reference counting, so simply deleting the tensor automatically handles storage deallocation when the last reference is removed.
