1. Add commitments to logs and update the `Display` implementation of `KzgCommitment` to become truncated similarly to block root.
I've been finding it difficult to debug scenarios involving multiple blobs for the same `(index, block_root)`. Logging the commitment will help with this, we can match it to what exists in the block.
Example output:
```
Oct 20 21:13:36.700 DEBG Successfully verified gossip blob commitment: 0xa3c1…1cd8, index: 0, root: 0xf31e…f9de, slot: 154568
Oct 20 21:13:36.785 DEBG Successfully verified gossip block commitments: [0xa3c1…1cd8, 0x8655…02ff, 0x8d6a…955a, 0x84ac…3a1b, 0x9752…629b, 0xb9fc…20fb], root: 0xf31eeb732702e429e89057b15e1c0c631e8452e09e03cb1924353f536ef4f9de, slot: 154568, graffiti: teku/besu, service: beacon
```
Example output in a block with no blobs (this will show up pre-deneb):
```
426734:Oct 20 21:15:24.113 DEBG Successfully verified gossip block, commitments: [], root: 0x619db1360ba0e8d44ae2a0f2450ebca47e167191feecffcfac0e8d7b6c39623c, slot: 154577, graffiti: teku/nethermind, service: beacon, module: beacon_chain::beacon_chain:2765
```
2. Remove `strum::IntoStaticStr` from `AvailabilityCheckError`. This is because `IntoStaticStr` end up dropping information inside the enum. So kzg commitments in this error are dropped, making it more difficult to debug
```
AvailabilityCheckError::KzgCommitmentMismatch {
blob_commitment: KzgCommitment,
block_commitment: KzgCommitment,
},
```
which is output as just `AvailabilityCheckError`
3. Some additional misc sync logs I found useful in debugging https://github.com/sigp/lighthouse/pull/4869
4. This downgrades ”Block returned for single block lookup not present” to debug because I don’t think we can fix the scenario that causes this unless we can cancel inflight rpc requests

## Issue Addressed
Makes lighthouse compliant with new kzg changes in https://github.com/ethereum/consensus-specs/releases/tag/v1.4.0-beta.3
## Proposed Changes
1. Adds new official trusted setup
2. Refactors kzg to match upstream changes in https://github.com/ethereum/c-kzg-4844/pull/377
3. Updates pre-generated `BlobBundle` to work with official trusted setup. ~~Using json here instead of ssz to account for different value of `MaxBlobCommitmentsPerBlock` in minimal and mainnet. By using json, we can just use one pre generated bundle for both minimal and mainnet. Size of 2 separate ssz bundles is approximately equal to one json bundle cc @jimmygchen~~
Dunno what I was doing, ssz works without any issues
4. Stores trusted_setup as just bytes in eth2_network_config so that we don't have kzg dependency in that lib and in lcli.

## Issue Addressed
Synchronize dependencies and edition on the workspace `Cargo.toml`
## Proposed Changes
with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies.
By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times.
## Additional Info
this PR also removes the no longer required direct dependency of the `serde_derive` crate.
should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged.

I think it's fine to not handle this since the calling functions handle the error.
No specific reason imo to handle it in the function as well.
* Rename BlobError to GossipBlobError
I feel this signified better what the error is for. The BlobError was only for failures when gossip
verifying a blob. We cannot get this error when doing rpc validation
* Remove the BlockError::BlobValidation variant
This error was only there to appease gossip verification before publish.
It's unclear how to peer score this error since this cannot actually occur during any
block verification flows.
This commit introuduces an additional error type BlockContentsError to better represent the
Error type
* Add docs for peer scoring (or lack thereof) of AvailabilityCheck errors
* I do not see a non-convoluted way of doing this. Okay to have some redundant code here
* Removing this to catch the failure red handed
* Fix compilation
* Cannot be deleted because some tests assume the trait impl
Also useful to have around for testing in the future imo
* Add some metrics and logs
* Only process `Imported` variant in sync_methods
The only additional thing for other variants that might be useful is logging. We can do that
later if required
* Convert to TryFrom
Not really sure where this would be used, but just did what the comment says.
Could consider just returning the Block variant for a deneb block in the From version
* Unlikely to change now
* This is fine as this is max_rpc_size per rpc chunk (for blobs, it would be 128kb max)

## Issue Addressed
Recent discussions with other client devs about optimistic sync have revealed a conceptual issue with the optimisation implemented in #3738. In designing that feature I failed to consider that the execution node checks the `blockHash` of the execution payload before responding with `SYNCING`, and that omitting this check entirely results in a degradation of the full node's validation. A node omitting the `blockHash` checks could be tricked by a supermajority of validators into following an invalid chain, something which is ordinarily impossible.
## Proposed Changes
I've added verification of the `payload.block_hash` in Lighthouse. In case of failure we log a warning and fall back to verifying the payload with the execution client.
I've used our existing dependency on `ethers_core` for RLP support, and a new dependency on Parity's `triehash` crate for the Merkle patricia trie. Although the `triehash` crate is currently unmaintained it seems like our best option at the moment (it is also used by Reth, and requires vastly less boilerplate than Parity's generic `trie-root` library).
Block hash verification is pretty quick, about 500us per block on my machine (mainnet).
The optimistic finalized sync feature can be disabled using `--disable-optimistic-finalized-sync` which forces full verification with the EL.
## Additional Info
This PR also introduces a new dependency on our [`metastruct`](https://github.com/sigp/metastruct) library, which was perfectly suited to the RLP serialization method. There will likely be changes as `metastruct` grows, but I think this is a good way to start dogfooding it.
I took inspiration from some Parity and Reth code while writing this, and have preserved the relevant license headers on the files containing code that was copied and modified.
## Issue Addressed
Updates discv5
Pending on
- [x] #3547
- [x] Alex upgrades his deps
## Proposed Changes
updates discv5 and the enr crate. The only relevant change would be some clear indications of ipv4 usage in lighthouse
## Additional Info
Functionally, this should be equivalent to the prev version.
As draft pending a discv5 release
## Issue Addressed
Which issue # does this PR address?
#2629
## Proposed Changes
Please list or describe the changes introduced by this PR.
1. ci would dowload the bls test cases from https://github.com/ethereum/bls12-381-tests/
2. all the bls test cases(except eth ones) would use cases in the archive from step one
3. The bls test cases from https://github.com/ethereum/consensus-spec-tests would stay there and no use . For the future , these bls test cases would be remove suggested from https://github.com/ethereum/consensus-spec-tests/issues/25 . So it would do no harm and compatible for future cases.
## Additional Info
Please provide any additional information. For example, future considerations
or information useful for reviewers.
Question:
I am not sure if I should implement tests about `deserialization_G1`, `deserialization_G2` and `hash_to_G2` for the issue.
## Issue Addressed
https://github.com/ethereum/beacon-APIs/pull/222
## Proposed Changes
Update Lighthouse's randao verification API to match the `beacon-APIs` spec. We implemented the API before spec stabilisation, and it changed slightly in the course of review.
Rather than a flag `verify_randao` taking a boolean value, the new API uses a `skip_randao_verification` flag which takes no argument. The new spec also requires the randao reveal to be present and equal to the point-at-infinity when `skip_randao_verification` is set.
I've also updated the `POST /lighthouse/analysis/block_rewards` API to take blinded blocks as input, as the execution payload is irrelevant and we may want to assess blocks produced by builders.
## Additional Info
This is technically a breaking change, but seeing as I suspect I'm the only one using these parameters/APIs, I think we're OK to include this in a patch release.
## Issue Addressed
NA
## Proposed Changes
I've noticed that our block hashing times increase significantly after the merge. I did some flamegraph-ing and noticed that we're allocating a `Vec` for each byte of each execution payload transaction. This seems like unnecessary work and a bit of a fragmentation risk.
This PR switches to `SmallVec<[u8; 32]>` for the packed encoding of `TreeHash`. I believe this is a nice simple optimisation with no downside.
### Benchmarking
These numbers were computed using #3580 on my desktop (i7 hex-core). You can see a bit of noise in the numbers, that's probably just my computer doing other things. Generally I found this change takes the time from 10-11ms to 8-9ms. I can also see all the allocations disappear from flamegraph.
This is the block being benchmarked: https://beaconcha.in/slot/4704236
