  Optionally return a StreamConnectionPair in StreamClientConnection::create
https://bugs.webkit.org/show_bug.cgi?id=261782

Reviewed by Kimmo Kinnunen.

Change function signature of `StreamClientConnection::create` to return
a `std::optional<StreamConnectionPair>`. Modify `StreamConnectionPair`
to use a `Ref<StreamClientConnection>` since the value will never be
`null`. Updated the call sites for `StreamClientConnection::create` to
handle the changes.

This is a step towards `SharedMemory::Handle` also always being valid.
