Add storage and device property getter AOTI shim functions to the header-only common_shims_slim library:

1. aoti_torch_get_storage_offset() - Returns the storage offset (SlimTensor: real offset, ETensor: always 0)
2. aoti_torch_get_storage_size() - Returns storage size in bytes
3. aoti_torch_get_device_type() - Returns device type (SlimTensor: real type, ETensor: CPU=0)
4. aoti_torch_get_device_index() - Returns device index (SlimTensor: real index, ETensor: 0)
