Implement Electra Fork

[ethDreamer]

This issue will track the tasks for implementing the Electra upgrade

We propose doing things differently in this fork. Instead of working off of a dedicated branch and having one big review and merge at the end, all PRs will target unstable directly and we will review and merge changes in one PR at a time. This means lighthouse must fully pass CI for each of these changes. We will not be able to turn on the Electra spec tests until Electra is fully implemented.

I've just opened a PR with the epoch processing changes. But I am yet to rebase the PRs that follow it in the conga line:
