Add support for AfterLastTestMethodErrored for use in Pest

[JHWelch]

I've been running into an error in Pest 4 that was reported a while back in 3.7.2 where AfterLastTestMethodErrored events are being passed into fromBeforeFirstTestMethodErrored.

Though the original issue was closed, if we look at Pest's source, it is simply ignoring a PHPStan error that this could happen.

} else {
    // @phpstan-ignore-next-line
    $state->add(TestResult::fromBeforeFirstTestMethodErrored($testResultEvent));
}

https://github.com/pestphp/pest/blob/08b09f2e98fc6830050c0237968b233768642d46/src/Support/StateGenerator.php#L34

To resolve this issue in Pest, Collision must support both kinds of test errors.

Because these errors seem like they can be handled in a common way, I created a single function that can receive both, but then kept the specific ones to not break backwards compatibility.

Pest could then take advantage of that single function to handle both cases and remove the PHPStan ignore

} else {
    $state->add(TestResult::fromTestErrorEvent($testResultEvent));
}

If this gets published I can follow up with the Pest PR in that repository.
