chore: Update PayloadID type to upstream geth core.beacon.PayloadID

[norswap]

See comment here: #127 (comment)

The type is now merged in geth (it's here: https://github.com/ethereum/go-ethereum/blob/20356e57b119b4e70ce47665a71964434e15200d/core/beacon/types.go)

This involves:

• rebasing our geth fork on top of geth 1.10.16
• updataing the imports
• changing the types

@protolambda does that look good? Want to do it? I'll do if necessary, just let me know.

There are other Engine API changes (mostly renames, and subtle effects to execution-layer syncing) that we'll also need to adopt if we rebase our geth diff on the latest version. For now I would prioritize keeping open sequencing PRs + blobs EIP moving. I could do the rebase/integration of latest geth after that.

Yes, I should have clarified, but this is not urgent. It was just in one my of my todo lists, and I thought I'd get it in the proper location :)

Closing this, this was implemented upstream long ago here: ethereum/go-ethereum#24236 and we use the type already.
