fix: Save genesis bootstrap congestion info into DB and reuse it at node restarts

[tayfunelmas]

This addresses #11702.

The issue happens for forknet and local testing where the network starts from the genesis block and the genesis protocol version supports congestion control. In this case, every time the node restarts, it attempts to re-generate the genesis congestion info. However, this is done using the state roots at genesis; these state roots are garbage collected and causes the bootstrapping to fail.

We fix this by storing the genesis congestion info (CongestionInfo for each shard) in DB. If it exists, the node directly uses it instead of attempting to re-compute it from state roots.

We store the congestion info in BlockMisc column with key GENESIS_CONGESTION_INFO.

This PR also adds a testloop test to check if the congestion info is saved (and not cleaned up by GC) and re-enables the previously disabled nayducks tests due to this problem.

LGTM
Can you add some debug logs when reading and storing the infos in the db? The bootstrapping already has a comment so no need to add another one there.
