new(tests): EOF - EIP-5450: RJUMP* vs CALLF tests

[pdobacz]

🗒️ Description

Adds a first batch of tests checking stack validation of these two kinds of operations RJUMP-ing and CALLF-ing (and RETF-ing ofc). I'm still missing JUMPF, but I want to go step by step as this has taken a while to prepare anyway.

First remark: I've decided to start off with an "automated" approach here, but as you'll see this has several complexities/inelegancies involved. There always is an alternative to just manually type out some interesting scenarios by hand, which we must bear in mind.

The problematic parts are:

• it would be quite hard for all the automatically generated codes to come with a 100% accurate max_stack_height, so I introduce a flag no_expecations_on_validity to eof_test. This is probably the biggest controversy, and I'm also still unsold on this, let's discuss more in the diff. The nice part is that somewhat automatically we get to test invalid and valid codes en masse, without spending too much time on figuring out the exact cases. EDIT: Thanks to Mario's fix and suggestions this is no longer the case
• it initially generated many many more tests, I've managed to trim this down aggressively to 400 768, however I took a - potentially unacceptable - shortcut and trimmed the "uninteresting" cases by pytest.skip. Without the pytest.skip it goes up to 800, all of the extra cases are ones which never successfully validate. All that being said, 400 is still a lot of cases, and I'd like to add JUMPF and recursive calls to this in the future iteration
• it is generally complex and has an air of "throw mud at wall, see if it sticks" and maybe gets into the court of what fuzzing should accomplish. Again, the "good part" of this is that we're not effectively re-writting the stack validation routines in EEST. EDIT: Again, Mario's fix and suggestion make it much less of a problem

I pushed some updates after incorporating the addition from ipsilon#3. Unfortunately, I've noticed that we should expand the tests by a little, I went to far while trimming and cut out some cases without which some RJUMP* snippets never validated. Now we're at 768 cases mark 😬.

Awesome, thanks for the changes, it's cleaner IMO.

This might need a rebase because now EOF tests are in the osaka folder.
