cmd/tailscale: add background mode to serve/funnel wip (#9202)

Browse Source 
> **Note**
> Behind the `TAILSCALE_FUNNEL_DEV` flag

* Expose additional listeners through flags
* Add a --bg flag to run in the background
* --set-path to set a path for a specific target (assumes running in background)

See the parent issue for more context.

Updates #8489
