[bisq-network/bisq] Envelope of envelopes (#2939)

[Florian Reimair]

Seeing an oszillating pattern of broadcast message numbers in [monitoring](https://monitor.bisq.network/d/wTDl6T_iz/p2p-stats?refresh=30s&orgId=1), @ManfredKarrer and I suspected that the pattern might be caused by the DoS protection mechanisms in place.

This PR introduces a new message that containing a number of existing messages. The hopes are:
- less connection setup overhead on the network level leading to less network load and hopefully better performance
- not to spread the bursts of e.g. RefreshOffer messages over a long time

In case this change has a bad effect on network stability (although we do not believe it is going to) we can simply remove the newly created `Capability` in a future release and thus, quickly get rid of the feature.
