chore(all): move eof from osaka to speculative

[spencer-tb]

🗒️ Description

As upset as I am with the decision, I am ripping the band-aid off fast. I hope we can include EOF in a future fork.

I've created a new folder within tests/ called speculative. This will contain tests for features that are not currently CFI'd for future forks. Verkle will sit here in the near future too.

I've created a new fork called EOFv1 for simplicity. This should be the only breaking change for filling and consuming existing EOF fixtures. Thus clients will need to add this fork. Evmone should additionally add this fork to fill the EOF tests.

A new label is added to EEST called fork:eof. I will relabel all the existing EOF PRs and issues with this.

And it is not included in Osaka yet?
