[LIBP2P] - Optimistically calculate VID when the primary network is down in `CombinedNetworks`

[lukaszrzasik]

What is this task and why do we need to work on it?

Currently VID is calculated by the DA node when VID is explicitly requested.

The task is to change it so that when the primary network is considered down, the DA nodes calculate VID in advance, not waiting for the explicit request.

What work will need to be done to complete this task?
