remove fake params from setcookie/setrawcookie

[schlndh]

Fixes phpstan/phpstan#10171

It turns out that this is wrong: #152 When I try to call setcookie with all 9 parameters it says that max 7 are accepted (PHP 8.2), named arguments such as samesite: 'lax' also don't work. I'm guessing that the arguments in the php_setcookie C function are there to cover the different variants + setcookie vs setrawcookie, but I haven't checked it.

However, the documentation states that the second signature, which takes an array as the third parameter, is not usable with named parameters.

The documentation is wrong about this - both variants seem to work with named arguments (at least on PHP 8.2).

[schlndh]

The wrong signature from functionMap triggered this condition:

phpstan-src/src/Reflection/SignatureMap/Php8SignatureMapProvider.php

Line 255 in 49f1667

continue 2;

that's why it was excluded from the named variants.
