Improve failed tests logging

[bee344]

We should log which tests fail for which chain, in order to facilitate coverage comparison between chains. The log should contain a summary for each chain with the amount of passed/failed/total tests, passing/ failing percentage, segregated by test suite (matter-labs/contracts). It should also specify which tests failed for each chain. We could also present the latter as the failed tests with a small indicator of for which chains it failed.

I see it looking something like this:

- <CHAIN>
- - Succesful Tests: ${amount} / ${percentage}
- - Failed Tests: ${amount} / ${percentage}
- Failed Tests
- - <FAILING-TEST-NAME> : <CHAINS>

These logs would be stored in a more permanent place and should only be updated when the tests situation changes. This should also facilitate picking only failing tests to rerun and save time.
