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.
