feat: add electra types

[morph-dev]

What was wrong?

We don't have any Pectra types defined.

How was it fixed?

I rebased #1763 and added few more things on top (rebase is first commit, mine is second):

• Added proper (I think) fork digest
  • I added test that checks that all fork digests are as expected (had to move some stuff around)
• Added pectra fork as part of the config
• Added more types to ef-tests
• Few other smaller changes

Planned work for the followup PRs:

• Add functions for creating HeaderWithProof based on Pectra types
• Add support for Pectra for HistoricalSummariesWithProof (see Add HistoricalSummariesWithProof for Electra portal-network-specs#397)
• Investigate if we have to update anything regarding validating beacon content post Pectra

To-Do

• Clean up commit history and use conventional commits.

@morph-dev please look at my review of the previous PR here, #1763 (comment)

impl ProcessBeaconBlock for SignedBeaconBlockElectra {
    fn process_beacon_block(&self) -> anyhow::Result<ProcessedBlock> {

is generating invalid execution headers

@morph-dev please look at my review of the previous PR here, #1763 (comment)

Yes, that's what I was planning on doing.

However, requests inside BeaconBlockBody are grouped by type, and I'm not sure in which order they should be iterated for execution header. I assume it would be "deposit requests" then "withdrawals requests" then "consolidations requests", but I'm not 100% sure.

Will look into it tomorrow...

Here is how it is performed in the consensus-spec https://github.com/ethereum/consensus-specs/blob/dev/specs/electra/beacon-chain.md#new-get_execution_requests_list

Thanks for the info! Done.
Ready for review.

I haven't verified if ForkName::Electra => [0xad, 0x53, 0x2c, 0xeb] is correct but other then that the PR looks good
