[slimtensor] Add common_shims_slim with basic property getters#16990
Conversation
Pull Request resolved: #16454 Add SlimTensor-based implementations of basic property getter AOTI shim functions: 1. `aoti_torch_get_data_ptr()` - Returns pointer to tensor data 2. `aoti_torch_get_sizes()` - Returns pointer to sizes array (SlimTensor stores int64_t directly) 3. `aoti_torch_get_strides()` - Returns pointer to strides array (SlimTensor stores int64_t directly) 4. `aoti_torch_get_dtype()` - Returns the scalar type as int32_t 5. `aoti_torch_get_dim()` - Returns the number of dimensions Key design: - Create a new common_shim_slim.h for working on new API while not impact the current pipeline. Will use common_shim_slim.{h/cpp} to replace current common_shim.{h/cpp} when everything has been set up. - Uses `#ifdef CUDA_AVAILABLE` conditional compilation to seperate the implementation between cuda backend and mps backend since SlimTensor hasn't have mps support yet. Will remove the branch once SlimTensor support mps. - Refactored to a header-only library so the caller's preprocessor flags determine which tensor type is used. This design supports both CUDA backend (SlimTensor) and MPS backend (ETensor) from a single library. ghstack-source-id: 336530252 @exported-using-ghexport Differential Revision: [D90126254](https://our.internmc.facebook.com/intern/diff/D90126254/)
