Review Comment:
It may be better that we don't export `TransportStatus` to users because we
have many useful macros for `arrow::Status` such as `ARROW_RETURN_NOT_OK()`.
Can we use `arrow::Status` directly?
It seems that `TransportStatus` may have `arrow::Status` via
`ArrowStatusDetail`.
Can we put `TransportStatus` into `arrow::Status::detail()` by creating
`TransportStatusDetail` or something?

Review Comment:
Can we use other constructor here?
```suggestion
: TransportStatus(code, "", {}) {}
```
