EVM: Add Mega EOF Examples

[holgerd77]

Related to #3440

Can we have one or two concise examples around EOF in the examples folder? Can eventually also just derived/adopted from the tests.

[jochem-brouwer]

Yes, will do! What did you have in mind here for the examples? I was thinking:

• Verifying if code is a valid EOF container
• Deploying EOF contract (via tx)
• Calling the EOF contract

[holgerd77]

Great, sounds good! 🙂 👍

Side question: WDYT, we cannot yet declare EOF as stable, or can we? If not, we should (I would then do) declare this in code docs, README and the like.

[jochem-brouwer]

We definitely cannot. In fact, we do not pass the latest execution-spec-tests. (I did not yet find the bandwidth to get deep into those bugs, tx refactor is taking it's time 😅 ).

In fact I should have explicitly marked it as unstable/experimental :)

Note; it also seems that the EOF spec is also not completely stable, with some edge cases/clarifications being merged.

[holgerd77]

Ok, I would have thought so (at the end it does not really matter if specs or we or both are not stable yet 😂 )!

Will update this along the release notes.
