Merge v1.12.1

[Tristan-Wilson]

Merge upstream geth's v1.12.1 release into our geth fork: https://github.com/ethereum/go-ethereum/releases/tag/v1.12.1

Merges were done with my gradual merging script to create a merge commit for the first conflict that is found: https://github.com/Tristan-Wilson/MyScripts/blob/main/bin/merge-helper. This makes for more merge commits but hopefully each one is easier to review.

Companion nitro PR: https://github.com/OffchainLabs/nitro/pull/1903

Testing done

geth and nitro tests pass.
