dev-middleware: Redefine "serverBaseUrl" as server-relative, '/json/list' by requestor

Summary:
`serverBaseUrl` is currently documented as:

> The base URL to the dev server, as addressible from the local developer machine

This is problematic in general because `dev-middleware` on a server doesn't necessarily know about where clients might be reaching it from, how tunnels or port-forwards are set up, etc., and this can change over the lifetime of the server and vary between clients.

Indeed, our own use of `serverBaseUrl` from both `community-cli-plugin` and internally simply sets it to the host and port the dev server is listening on - ie it's the address of the dev server accessible *from the server*.

This PR changes the docs, redefining `serverBaseUrl`, to match the way we currently specify it.

One usage where we *do* want the previously documented behaviour is in responses to `/json/list` (`getPageDescriptions`) where the URLs in the response should be reachable by a browser requesting `/json/list`. 

Here, we use the request (host header, etc.) to attempt to get working base URL.

History:
It should be mentioned that this is the latest in a series of changes like this:
 - https://github.com/facebook/react-native/pull/39394
 - https://github.com/facebook/react-native/pull/39456

Learning from those:
 - This change does *not* break Android emulators, which routes `10.0.2.2` to localhost, or other routed devices, because `/open-debugger` still uses server-relative URLs, and now formally delegates to `BrowserLauncher` to decide what to do with those URLs (internally, VSCode / `xdg-open` handles port forwarding)
 - Middleware configuration is no longer required to specify how it is reachable from clients.

This sets up some subsequent changes for more robust handling of tunnelled connections.

Changelog:
[General][Breaking] dev-middleware: Frameworks should specify `serverBaseUrl` relative to the middleware host.
