argument.invalidConstant changes valid RoundingMode::HalfAwayFromZero enum #14716

Bug report

Just updated to 2.2.0 and ran PHPStan again, which wanted to change:

$leaveOver = (int) round($totalCount / 2, 0, \RoundingMode::HalfTowardsZero);
to
$leaveOver = (int) round($totalCount / 2, 0, PHP_ROUND_HALF_DOWN);

The former being the modern way: https://www.php.net/manual/en/function.round.php

Rector wants to change this back again to the enum btw. Which I think is the right choice here.
