[Epic: nwaku] add nwaku into status-go

[Ivansete-status]

Summary

https://github.com/status-im/status-go should operate with waku through nwaku

We need to add a new nwaku submodule within status-go and adapt the current status-go code base plus nwaku-libwaku so that we can have status-go working with nwaku.

There will be changes in:

• status-go to integrate nwaku
• nwaku to extend libwaku with the features needed by status-go

Tasks

• feat: nwaku in status-go (discv5 and dnsdiscovery) nwaku#3039
• chore: nwaku should be a submodule of status-go nwaku#3052
• chore: store in status-go through nwaku nwaku#3053
