[Feature Request]: Make NodeInfo Optional on WantConfig

[garthvh]

Platform

NRF52, ESP32

Description

Right now want config also returns the whole nodedb, which is usually 100 when nodes are on MQTT, would be great for the apps and things like the Arduino library if we could have the want config just bring back the config and do the node info separately after we have got config data back.

[garthvh]

Still need a way to get just the nodedb now

Let's close this in favour of #4564
