Update vizio app_id state attribute to show app config dict instead of app name

[raman325]

Proposed change

This PR updates the app_id state attribute to show the config properties needed to identify an app. It is possible for the user to manually configure the app for detection in HA (when pyvizio can’t detect the app name natively) using the configuration provided by the Vizio API, but this previously required users to install and run pyvizio locally whereas now users can get this information from Home Assistant directly.

I'm also reducing the number of calls to the Vizio API from 2 to 1 by simplifying the logic to retrieve the app name

Per @MartinHjelmare 's feedback on #33051 I will be submitting a separate PR to remove the conditional logic out of my test helpers. So when reviewing this PR please ignore that issue for now, as it will require significant changes and will be easier to submit and review separately.
