* reworked some of the das core specs, pr'd to check whether whether the conflicting type issue is centric to my machine or not
* bumped nim-blscurve to 9c6e80c6109133c0af3025654f5a8820282cff05, same as unstable
* bumped nim-eth2-scenarios, nim-nat-traversal at par with unstable, added more pathches, made peerdas devnet branch backward compatible, peerdas passing new ssz tests as per alpha3, disabled electra fixture tests, as branch hasn't been rebased for a while
* refactor test fixture files
* rm: serializeDataColumn
* refactor: took data columns extracted from blobs during block proposal to the heap
* disable blob broadcast in pd devnet
* fix addBlock in message router
* fix: data column iterator
* added debug checkpoints to check CI
* refactor if else conditions
* add: updated das core specs to alpha 3, and unit tests pass
The fallback when blobless quarantine contains a block with all blobs
modifies collection while iterating, potentially asserting if reachable.
Using a second loop to process this situation resolves that.
When checking for `MissingParent`, it may be that the parent block was
already discovered as part of a prior run. In that case, it can be
loaded from storage and processed without having to rediscover the
entire branch from the network. This is similar to #6112 but for blocks
that are discovered via gossip / sync mgr instead of via request mgr.
When restarting beacon node, orphaned blocks remain in the database but
on startup, only the canonical chain as selected by fork choice loads.
When a new block is discovered that builds on top of an orphaned block,
the orphaned block is re-downloaded using sync/request manager, despite
it already being present on disk. Such queries can be answered locally
to improve discovery speed of alternate forks.
When the requestmanager is busy fetching blocks, the queue might get
filled with multiple entries of the same root - since there is no
deduplication, requests containing the same root multiple times will be
sent out.
Also, because the items sit in the queue for a long time potentially,
the request might be stale by the time that the manager is ready with
the previous request.
This PR removes the queue and directly fetches the blocks to download
from the quarantine which solves both problems (the quarantine already
de-duplicates and is clean of stale information).
Removing the queue for blobs is left for a future PR.

Post-Deneb, when the request manager receives a missing block from a
peer, it needs to check if the corresponding blobs are available, and
if so pass them along. If they aren't available, the newly-fetched
block must be put in blobless quarantine (while the blobs are
retrieved, coming in next commit).
* Update sync to use post-decoupling RPCs
blob_sidecars_by_range returns a flat list of sidecars, which must
then be grouped per-slot.
* Add test for groupBlobs
* createBlobs: convert proc to func
Other changes:
Renamed the `EIP_4844_FORK_*` config constants to `DENEB_FORK_*` as
this matches the latest spec and it's already used in the official
Sepolia config.
While syncing the finalized portion of the chain, the execution client
cannot efficiently sync and most of the time returns `SYNCING` - in this
PR, we use CL-verified optmistic sync as long as the block is claimed to
be finalized, only occasionally updating the EL with progress.
Although a peer might lie about what is finalized and what isn't,
eventually we'll call the execution client - thus, all a dishonest
client can do is delay execution verification slightly. Gossip blocks in
particular are never assumed to be finalized.
The various `PeerScore` constants are used for both beacon blocks and
LC objects, and will likely also find use for EIP4844 blob sidecars.
Renaming them to use more generically applicable names not referring
to blocks explicitly aymore.
We currently use `BlockError` for both beacon blocks and LC objects.
In light of EIP4844, we will likely also use it for blob sidecars.
To avoid confusion, renaming it to a more generic `VerifierError`,
and update its documentation to be more generic.
To avoid long lines as a followup, also renaming the `block_processor`'s
`BlockProcessingCompleted.completed`->`ProcessingStatus.completed` and
`BlockProcessingCompleted.notCompleted`->`ProcessingStatus.notCompleted`
