restore doppelganger check on connectivity loss (#4616)
* restore doppelganger check on connectivity loss

https://github.com/status-im/nimbus-eth2/pull/4398 introduced a
regression in functionality where doppelganger detection would not be
rerun during connectivity loss. This PR reintroduces this check and
makes some adjustments to the implementation to simplify the code flow
for both BN and VC.

* track when check was last performed for each validator (to deal with
late-added validators)
* track when we performed a doppel-detectable activity (attesting) so as
to avoid false positives
* remove nodeStart special case (this should be treated the same as
adding a validator dynamically just after startup)

* allow sync committee duties in doppelganger period

* don't trigger doppelganger when registering duties

* fix crash when expected index response is missing

* fix missing slashingSafe propagation

The sync committee duties loop now starts after fork info to be available (#4355)
This is needed because the service needs to call `forkAtEpoch()` as part
of its operation.

Bugfix: The VC was producing invalid sync committee contributions (#4343)
Since the sync committee duties are no longer updated on every slot
and previously the sync committee aggregators selection proofs were
generated during the duties update, this now resulted in the client
using stale selection proofs (they must be generated at each slot).

The fix consists of moving the selection proof generation logic in
a different function which is properly executed on each slot.

Other changes:

* The logtrace tool has been enhanced with a framework for adding
  new simpler log aggregation and analysis algorithms.
  The default CI testnet simulation will now ensure that the blocks
  in the network have reasonable sync committee participation.
