Ignore failing tests from bad gas limit config

[Nashtare]

Not very important, but in the resulting test_pass_state CSV file from running the plonky2_runner, a lot of "Failed" results happen to arise from tests which we cannot verify because of the design choice of supporting only 32-bit gas limits.

As such, I'm proposing to have a dedicated TestPass variant called Ignored purposedly for this failure case, to trim the number of false negatives.

For the record, I'm also running the whole suite against the latest main and the changes from this branch, to make sure those ignored tests wouldn't reveal some failing edge cases.

Yeah this seems like a reasonable way to handle this. I think it might be slightly cleaner to filter these out in the parser instead when we parse the test *.json --> *.cbor, but this is more than fine. Thanks for adding this!
