Rebase onto 1.10.21

[ABastionOfSanity]

1.10.21 has been released, we need to update our custom geth client to work on top of this release.

We need to perform the rebase only the v4 version (and the v5 will be built on top of it).

• v4 on top of v1.10.19-statediff-v4.2.0: Rebase statediff v4 onto v1.10.20 #258

After cutting a release, we will to update the following repos to use these releases:

• eth-statediff-service
• ipld-eth-server
• ipld-eth-db-validator
• ipld-eth-state-snapshot
• eth-statediff-fill-service

We will also need to update and release versions of the following repos that use the root v1.10.20 release:

• ipfs-ethdb
• leveldb-ethdb-rpc
• go-eth-state-node-iterator
• eth-ipfs-state-validator

NOTE:

• Update these first, as multiple others depend on them: ipfs-ethdb, go-eth-state-node-iterator
• ipld-eth-db-validator depends on ipld-eth-server, so ipld-eth-server needs to be updated prior.

Some changes that necessitate changes in our stack, aside from rebasing our release of this repo and propagating those:

• ipld-eth-server updates to API to stay compatible: go-ethereum v1.10.21 API updates ipld-eth-server#177

All repos involved updated, github actions updated, and releases cut. Lots of dependency updates here.
