feat[devtools]: add method for connecting backend with custom messaging protocol (#28552)

## Summary

RDT backend will now expose method `connectWithCustomMessagingProtocol`,
which will be similar to the classic `connectToDevTools` one, but with
few differences:
1. It delegates the communication management between frontend and
backend to the owner (whos injecting RDT backend). Unlike the
`connectToDevTools`, which is relying on websocket connection and
receives host and port as an arguments.
2. It returns a callback, which can be used for unsubscribing the
current backend instance from the global DevTools hook.


This is a prerequisite for any non-browser RDT integration, which is not
designed to be based on websocket.
