support mysqli_execute_query (php 8.2+ only)

[staabm]

closes #409

requires #426

[staabm]

the test fails because the rule involved runs into this early exit

phpstan-dba/src/Rules/SyntaxErrorInQueryMethodRule.php

Lines 47 to 50 in f60f559

	$methodReflection = $scope->getMethodReflection($scope->getType($node->var), $node->name->toString());
	if (null === $methodReflection) {
	return [];
	}

I guess it will work with the next phpstan version which has updated php8 stubs
