Use host-relative WebSocket URLs when launching new debugger

[motiz88]

Summary: Changelog: [Internal]

Uses the capability introduced in https://github.com/facebookexperimental/rn-chrome-devtools-frontend/pull/4 to avoid repeating the dev server's host:port in the ws / wss parameter we pass to the Chrome DevTools frontend. This gives us more flexibility to handle port forwarding and redirects outside of dev-middleware. This is mostly useful in Meta's internal VS Code remoting setup, but this particular change should work equally well in open source.
