Add non-owning constructor to MaybeOwningStorage that allows wrapping external memory without taking ownership. This is needed for from_blob() which creates tensors from user-provided data pointers. Changes: - Add MaybeOwningStorage(device, data, nbytes) non-owning constructor - Add is_owning() method to query ownership mode - Non-owning storage uses no-op deleter so external memory is not freed Differential Revision: [D91202898](https://our.internmc.facebook.com/intern/diff/D91202898/) [ghstack-poisoned]
