Refactor `PortInUseException` logic to a single place and refine when
the exception is thrown.
Prior to this commit, we assumed that a `BindException` was only thrown
when the port was in use. In fact, it's possible that the exception
could be thrown because the requested address "could not be assigned".
We now only throw a `PortInUserException` if the `BindException` message
includes the phrase "in use".
Fixes gh-21101
