Update arginfo for preg_match_all() to reflect reality.

Back when I implemented FR #53238 during the 5.4 development phase to make the
$matches parameter optional in preg_match_all(), it turns out I forgot to
update the arginfo to note that only 2 parameters are now required by
preg_match_all(). The function itself works fine, but reflection was reporting
the wrong number of required parameters.
