new(tests): EOF - EIP-7620: RETURNCONTRACT validation tests

[gumb0]

🗒️ Description

This migrates RETURNCONTRACT validation tests from ethereum/tests.

Note: according to the latest spec these cases are valid only for "initcode" containers, and next step would be to support initcontainer flag in test fixtures - see the branch https://github.com/ipsilon/execution-spec-tests/tree/eof-returncontract-initcode

but I still can't fill the tests. ah is it because test generation fails because it requires specific evmone branch? the script rely that the tests are fillable with latest evmone

Hey @gumb0 could you rebase and push to see if that fixes the CI please?

[marioevz]

Also coverage fix is now merged in main, so that should be removed from this PR on rebase and we should be good to merge.

Any fixes needed here?

[chfast]

The latest evmone master branch fails to generate this tests.

I believe this is fixed now.
