Fix: Regression in the `cmConditionEvaluator::HandleLevel0`

As reported in the BUG #22524, mismatched parenthesis reported differently
for `while()` and `if()`.

The problem was in the double loop (over "handlers" and the arguments),
where the outer loop didn't check the result of the running handler.
