Create a nullable object having the same value as the specified `original` object by moving the contents of `original` to the newly‐created object. If `TYPE` takes an optional allocator at construction, the allocator associated with `original` is propagated for use in the newly‐created object. `original` is left in a valid but unspecified state.
